Deaths in Los Alamos During the Manhattan Project

6/17/2023

2 Comments

 
There are two well-known deaths that are associated with Los Alamos from the time of the Manhattan Project, Harry Daghlian and Louis Slotin. Both of these deaths were caused by criticality accidents while handling the “demon core”. What many people do not know is that there were 22 more deaths that occurred in Los Alamos during the Manhattan Project. 

These 24 deaths were accidents relating to construction, motor vehicle crashes, persons hit by cars, accidental firing of a weapon, a drowning, a fall from a horse, an overdose, the radiation incidents, alcohol poisoning, and missupervision leading to a smoke bomb explosion. 

A blog post was made about these accidents on the Nuclear Secrecy blog, and it led to our researcher looking in the archives to see if we had reports of these accidents. They found little articles in the local newspaper reporting Slotin’s condition and death, and maybe a notice or two for the other deaths that happened after the war was over. 

It is difficult to verify the presence of these people during the Manhattan Project because we have the images of the security passes for the civilians (in which there are several errors), but barely any record for the military personnel. Our researcher then used a national digital repository of newspapers, and digital military databases to find out more. Here is what they found:
February 11th, 1943 - Estevan Roches was working a bulldozer at night to clear rock and dirt to help widen the road to the project. The hillside was ‘blasted’ 30 minutes prior, and a safety team had given the all clear after searching for loose boulders that may fall. It is guessed that the vibrations from the machines caused the boulder to fall onto Estevan and his bulldozer. An investigation absolved the supervising company of blame because the safety precautions had been taken, but future blasting and clearing operations were to be done during daylight hours (even though the site was well lit at the time). 
Roches was 28 at the time of death, draft card stated that he resided in Santa Fe, NM death index states that he died in Espanola, Sandoval County, NM.

March 1st, 1943 - George Herman Holtary was caught against a crankshaft and its housing. It took about 10 minutes to rescue him from the 13,000 pound pressure of the crankshaft. An ambulance took him to Santa Fe but he died enroute. The supervising company was absolved of blame because Holtary went against protocol and went to replace a piston by going inside the crankcase when it was normally replaced from the outside. 
The NM death index lists his death as being in Espanola, Sandoval County, NM.

July 19th, 1943 - George J. Edwards fell into a drainage ditch while walking in town on July 5th. The fall injured his back and he wasn’t found until the next morning. He was sent to Bruns Hospital in Santa Fe and it was found that he had a punctured kidney. He died two weeks later. 
    Edward’s National Cemetery Interment Control Form lists his death as happening in Los Alamos, NM. The internment card and the NM death index both list his death as being July 15th, which contradicts the Manhattan Project report. This is unusual because secrecy was being enforced up on The Hill, and Los Alamos was no longer being listed on maps. 

November 2nd, 1943 - Jose Montoya was digging an acid sewer ditch, which was 8 feet deep, and either didn’t hear or disregarded his foreman’s order to get out of the ditch. The ditch was not reinforced so it caved in and buried Montoya in 6 feet of dirt. Efforts to unbury him were immediate but he was dead when removed. 
    More research would be needed. There were multiple 39 year old Jose Montoyas from NM that were in World War Two, and no clear death records were found. 

November 4th, 1943 - Pfc Frederick W. Galbraith Jr. was accidentally shot by a rifle. His colleague did not know that there was a cartridge in the chamber and was cleaning his rifle. Galbraith was asleep in a bed near the colleague and was shot in the thigh. The injury was severe due to the angle of entry, so immediate medical aid was administered and he was transported to Bruns Hospital in Santa Fe. “Galbraith died from severe shock as a result of the wound”. He was 31 years old.
    A published obituary and the NM death index state that he died in Santa Fe, NM. Galbraith is buried in Queens, NY.

November 20th, 1943 - Efren Lovato was riding in/on a Chevrolet dump truck that was being used as a transport vehicle for 28 laborers. The truck was approaching a gate entrance when the accelerator pedal got stuck, and the foot and hand brakes couldn’t stop the vehicle. The driver attempted to drive between the gate and a parked vehicle, which caused the truck to overturn. Lovato was injured when the vehicle overturned, and later died at the post hospital due to a laceration of the lung.
    The NM death index listed his whole name as Jose Efren Lovato, and that he died in Los Alamos, NM.

November 20th, 1943 - Fridon Vigil was in the same incident as described above, however he died due to laceration of the brain. His name in the document is difficult to read, so this is likely a misspelling of his name. This also means that we were unable to find more information about him in our research.

May 9th, 1944 - Fred K. Wolcott was killed in a tree felling incident. He did not try to get out of the way and as a result was killed instantly upon contact with the upper branches of the tree as it fell onto him and his bulldozer. The official cause of death was labeled as brain and internal chest injuries. 
    The NM death index states that he passed away in Sandoval County, NM.

July 1st, 1944 - Elmer R. Bowen Jr. was 10 and a half years old and a son of a civilian employee. He went canoeing on Ashley Pond and the vessel capsized. Bowen did not know how to swim and did not grab the life preserver that was in the canoe. Life saving efforts were attempted for 2 hours but were unsuccessful. Several residents remember this as being the reason for a ban on swimming or canoeing on Ashley Pond for many, many years.
    The NM death index records his death as being in Sandoval, NM.

July 6th, 1944 - Ernesto Freques was a truck driver employed by a local construction contractor. His truck was being loaded with steel reinforcing mesh, but there were difficulties. Fresques was standing between the loading area of the steel and his truck when a section of the pile toppled over and pinned him against the truck. He died instantly due to a laceration of the heart and lungs.
    He was 25 years old, and the NM death index has him recorded as having died in Sandoval County. 

August 5th, 1944 - Horace Russell Jr., age 26, was thrown off his horse while riding in a canyon off site. The head injury he suffered was later identified as a laceration of the brain. The NM death index lists his death as being in Santa Fe, NM.

December 3rd, 1944 - Pfc Hugo B. Kivisto was a PED and died as a result of being pinned beneath his vehicle after trying to escape it as it drove over the edge of an embankment. This is likely the same area where previous automobile accidents happened. He died from multiple hemorrhages of the brain, multiple injuries of the head, and possible suffocation. 

July 21st, 1945 - Pvt Grover C. Atwell was an SED and was assigned to the hospital as a ward attendant. He died from an overdose of barbiturates that were taken from the hospital pharmacy. The report states that his body was discovered a month later on August 22nd, but this may be an error. His body was taken to Bruns Hospital for an autopsy. He was 20 years old when he died.

August 7th, 1945 - James M. Popplewell was a civilian carpenter working inside a building when a caterpillar pushed dirt over the roof. The combined weight of the caterpillar and the dirt caused the roof to cave in. The machine pinned Popplewell and caused his instant death by breaking his neck and strangulation. The sub-foreman was held responsible for not ascertaining if the roof would be strong enough to hold the “cat” and for leaving the site while the work was being done. 
    Popplewell was sent to Texas and services were held in Dallas. His obituary stated that he worked at “Camp Los Alamos, near Santa Fe, NM”. This publication was 3 days after the Little Boy bomb was dropped, and on the same day the Fat Man was dropped. Los Alamos had been written about on August 6th so it was no longer a secret city.

September 15th, 1945 - Harry K. Daghlian and his incident are written about by the Atomic Heritage Foundation here:
ttps://ahf.nuclearmuseum.org/ahf/profile/harry-daghlian/. 


October 6th, 1945 - Asa S. Houghton was driving down from the Hill when his brakes locked and his car ran off the road, off a 250 foot embankment, and rolled 5 or 6 times. He was taken to the post hospital and was found to have a broken collar bone, broken ribs, and internal injuries. He lived for 6 days before succumbing to his injuries. Further research did not produce any official documents.

January 29th, 1946 - Manuel Salazar was a janitor employed on the project and was on duty. He was visited by Asa Houghton and Manuel Salazar (also janitors but not on duty) and the three of them drank Ethylene glycol(anti-freeze) mixed with muscatel wine. The three of them became violently ill, and were taken to the Project’s hospital for treatment. The treatment failed and they died due to “injury to internal organs caused by poison contained in ethylene glycol”. Salazar died at 1235 hours. He had been discharged 3 months prior after having served during the war. 

January 29th, 1946 - Alberto Roybal was involved in the incident described above. He died at 1445 hours. He was 46 years old and is buried in Pojoaque Cemetery. 

January 29th, 1945 - Pedro Baca was involved in the incident described above. He died at 1500 hours. 

February 6th, 1946 - Levi W. Cain was hit by a car while crossing Main Street at a location with poor visibility. He was sent to the local hospital and complained of a severe backache. He died from a fracture dislocation of the spine and severance of the spinal cord.
    His obituary that was printed in Kansas stated that he had an injury 26 years prior that left him a “cripple”, and that he was hit in Santa Fe, NM. He was 52 years old. 

May 21st, 1946 - Louis Slotin and his death are written about here: https://www.losalamoshistory.org/history-blog/the-slotin-accident-inside-the-archives 

July 1st, 1946 - Livio R. Aguilar was driving a 2 and a half ton government vehicle when it left the road and turned over into a pipeline trench. Aguilar likely died almost immediately due to “multiple fractures of the facial bones and complete flattening of the right side of skull”. He was 25 years old and was buried in Albuquerque.

August 2nd, 1946 - Joshua Isaac Schwartz was assigned to trace air currents in Omega Canyon. He went against instructions to use balloons or other non-flammable equipment by using a smudge-pot (made up of potassium chlorate, sugar, red phosphorus and magnesium turnings) which exploded. It fatally injured Schwartz and critically injured his colleagues.
    The obituary said that he died on the 3rd, and died as a result from a premature explosion of pyrotechnic chemicals. He was 21 years old and is buried in Brooklyn, NY.


August 7th, 1946 - Herbert G. Schwaner was pinned under a bulldozer after trying to drive it up a ramp onto a trailer. He was found by his brother 5 minutes later and was pronounced dead when the doctors arrived.

Almost all of these deaths were not reported in the Daily Bulletin that was distributed on the Hill during the war.

George T. May III and His Family's Donation.

Did you see the article about us in the Daily Post? 

We had some very special guests in our archives on March 24th. Some of the remaining family of George T. May III (nicknamed Tertius) visited our archives with a donation. For decades, the family has kept Tertius’ items from his years at the Los Alamos Ranch School. 

George Thomas May III was born in 1903. According to his niece, “Terk was a sickly child who suffered from severe asthma and spent much of his childhood in Illinois as an invalid”. Because there were not many effective treatments for those suffering with asthma, many were sent away from home to Western states that had cleaner air. Terk was sent to Los Alamos in 1919 at the age of 15. A letter from A. J. Connell, who was the director of the Los Alamos Ranch School, dated October 7th, 1919 states that “He has not had any asthma since the little attack I told you of when he first came here, His weight is now 85 pounds, a gain of 9 pounds since his arrival June 16th. He also shows 1.2 inch gain in height. He shows slight gains in practically all measurements and much in endurance.” Several accommodations were given to Terk during his time in Los Alamos, and there is only one known mention of Terk needing medical assistance from somewhere offsite of the Los Alamos Ranch.

Los Alamos and Daylight Savings Time

Did you know that Los Alamos was the only county in the state of New Mexico to participate in Daylight Savings Time (DST) for many years?

    In late April of 1946, a census was collected within Los Alamos regarding the adoption of Daylight Savings Time. In 1950 it was announced by the Atomic Energy Commision (AEC) that Los Alamos and the construction camp of White Rock would begin DST. Las Vegas had tried DST in May of 1946, but ultimately ended up reverting back to Standard time in July of the same year. No connection has been found yet between the efforts of Las Vegas and Los Alamos towards adopting DST.

Our Two Main Roads

This image was taken during the Ranch School era. The camera is facing East and you may recognize the two parallel roads. Be sure to notice where these roads merge together in the distance.
Downtown Los Alamos revolves around two roads, Trinity Drive and Central Avenue. These two roads run parallel to each other and they handle a majority of the traffic for everyday Los Alamos. Our small businesses, restaurants, and some of our residences rely on these roads. When one of them requires construction, the town is thrown into an uproar because our ‘traffic’ builds up for several blocks, blocking the ease of flow for the town. 

A little known fact is that these streets have been here almost as long as the town has! Granted, there have been a few bends here and there, but the overall location and direction has remained the same since the era of the Los Alamos Ranch School (1917 to 1943).

Transportation and Preparation for the Atomic Bombs

We remember the Trinity test as the changing point for the future of weapons development and the course of the Second World War. The basic details are frequently talked about; it was the first major test of the implosion design, it was successful, it occurred on July 16th 1945, etc, but the steps taken in preparation for this test are not often discussed. 

A test explosion was conducted in May of 1945 at Trinity site to do a dry run with the measurement and photographic equipment. 100 tons of TNT were detonated 20 feet off the group atop of a wooden structure. The test was a success, although the explosion was about a 20th in size in comparison to the well known explosion that would take place 2 months later.

Otowi Site

​Living on the Los Alamos Plateau always brings forth curiosities, but some of the biggest ones are our local Ancestral Puebloan Sites. No matter where you are in town you will be within a several hundred-foot proximity to ones of these sites, or at least where one used to be. Excavations and preservation efforts have been conducted in Los Alamos for over 100 years.
One of the largest sites within our county is the Ancestral Puebloan Site named Otowi, also claimed to have been called Potsuwi’I which means ‘gap where the water sinks’. Acquired from some old newspaper publications, one of the first excavations of this location started in 1915 by a woman named Lucy Langdon Williams Wilson. She was the principal of a school in Philadelphia and her husband ran the Philadelphia Commercial Museum. With some basic paperwork and a 3-year governmental permit, they set out west to excavate Otowi.

Inside the Archives: Hilltop House

9/8/2021

If you have lived in Los Alamos for very long, then it is likely you have run into someone who has used a building as a landmark when giving you directions. Now, whether that building is still in existence or the business names they use still occupy the space is a different story entirely. It could be “turn by the Conoco hill gas station,” or “just past the Hill Diner,” or “where the Los Alamos Inn used to be.” Whatever it may be, landmark buildings are a guidepost for our everyday lives. This month we’re digging #InsideTheArchives to a landmark that stands at the entrance to Los Alamos, welcoming visitors and locals alike: the Hilltop House Motel.

The Hilltop House Motel was built in the mid-1970s and had significant additions, such as a restaurant, made to it in 1980–1981. The Hilltop House’s annex was added in the mid/late 1980s and was just across Central Ave. The business closed in 2013 and the building has changed hands a couple times, but remains vacant at this time.
 
What are your memories of the Hilltop House Motel? Did you ever stay there? Did you eat at one of the restaurants housed there (can you remember their names)? Help us bring this Los Alamos landmark to life with your stories in the comments.

Come Inside the Archives with us this month to check out one of our most recent donations. These images are digitized copies of some of the slides donated by Betty Pickens Cabber, the daughter of Homer and Edna Pickens. Can you help us identify any of the people (or animals) in these photos?
A crowd of children in winter coats gather closely around the back of a white pickup truck with a large wooden crate affixed in the truck bed. A person wearing a cowboy hat stands in the bed of the truck, bent at the waist seemingly showing something to the children. Two bikes are parked in the foreground.

Los Alamos has many treasured community members, one of whom is Bun Ryan (Dec. 23, 1923-Sept. 29, 2014) who was named a Living Treasure of Los Alamos in 1999. Bun Ryan is famous in Los Alamos for his fast pitches as part of the Pierotti’s Clowns, but his contributions to Los Alamos history don’t end there.
Three men sit at the far end of a wooden table, smiling and holding pens and softballs. Green boxes of softballs sit on the table closest to the camera. In the background are shelves full of archival boxes.
