Floy Agnes Lee, called Aggie, was a hematology service technician at Los Alamos. Hired to the Manhattan Task right out of university, she gathered blood examples from numerous Manhattan Task researchers, consisting of the prominent physicist Enrico Fermi. Years after the battle, she went back to Los Alamos National Lab to research the results of radiation on the body.


[New to Lost Women of Science? You can listen to our most recent Short here and our most recent multi-episode season here.]


Floy Agnes Lee: It remained in 1945, as well as the bomb was being created back then.

As well as my task was to take, gather the blood from the study guys that, researchers that were working with the atomic bomb.

Katie Hafner: This is Lost Female of the Manhattan Task. Which’s the voice of Floy Agnes Lee, that began operating at Los Alamos National Lab in 1945, a year that specified a previously as well as after. A globe prior to nuclear tools as well as a globe after.

This unique collection concerning ladies that dealt with The Manhattan Task is various from what we typically do. Normally we make every effort to enlighten while likewise amusing you, as well as we constantly placed our tales versus the background of just how ladies were pertained to as well as dealt with at the time in which they lived. Yet in this unique collection, the only background you require is the background of necessity, the necessity of battle, as well as just how ladies signed up with the battle.

In this, the 2nd in our collection, we radiate a light on Floy Agnes Lee, called Aggie, an aboriginal girl that originated from the Santa Clara Pueblo country as well as signed up with the Manhattan Task right out of university. Her work was taking as well as evaluating researchers’ blood. This might appear easy, yet Los Alamos was a harmful location to function, as well as it was extremely deceptive.

Most Of those that functioned there were not informed that what they were, actually, assisting to develop was an atomic bomb. Aggie Lee was amongst those individuals maintained in the dark, yet she saw firsthand the dreadful results of radiation direct exposure on the body. Which transformed her life. She took place to invest the majority of clinical job examining the results of radiation.

Manufacturer Monica Lopez brings us the tale.

Monica Lopez: Floy Agnes Lee was birthed July 23, 1922, the kid of a German American mom from Indiana as well as a papa from Santa Clara Pueblo simply northeast of Los Alamos. Her mom as well as daddy fulfilled at the Indian Boarding Institution where they both functioned.

Floy Agnes Lee: She came as an educator to educate in the boarding institution in Santa Fe as well as fulfilled my Indian daddy that was educating customizing, which he had actually found out there.

Monica Lopez: They wed in Colorado as well as sent out wedding event invites to loved ones in Indiana after the event.

Floy Agnes Lee: Due to the fact that they understood that my, white loved ones would certainly challenge her weding an Indian.

Monica Lopez: Among 5 brother or sisters, Aggie matured at the Indian boarding institution in Albuquerque as well as participated in courses at St. Mary’s Catholic Institution.

Floy Agnes Lee: The religious women would certainly originate from the eastern as well as to educate as well as. They would certainly discuss the savages at the Indian institution since that’s all they understood that the Indians were called savages. Which actually reached me, you recognize.

Monica Lopez: Yet Aggie boasted of her native heritage. She took place to Albuquerque Senior High School, and afterwards to the College of New Mexico as well as examined biology. Aggie’s daddy urged her to sign up with the army to aid spend for university. She tried for the Female’s Airforce Solution Pilots, or WASPS, as well as was approved right into the trip training program.

Floy Agnes Lee: I took flying lessons, soloed as well as prepared to enter into the Female’s Flying force, yet I had another maneuver to make prior to I might go, which was to do go across nation.

Monica Lopez: Aggie intended to proceed trip training, yet prior to she had the ability to finish it, another thing came suddenly.

Floy Agnes Lee: When I finished from college, the teacher, that was head of the biology division, asked me to remain one more month and afterwards he asked me would certainly I such as to head to Los Alamos as well as function there. As well as I did not work aligned, so I claimed yes. To make sure that’s just how I reached Los Alamos.

Monica Lopez: Aggie signed up with the Manhattan Task in the hematology laboratory in 1945. She entered into what the United States Division of Power called “among the nation’s solitary biggest wartime business.” Danish Physicist Niels Bohr had as soon as claimed that for the united state to develop an a-bomb, they would certainly need to transform the nation “right into one massive manufacturing facility.” As well as they almost did. At its top, the Manhattan Task used 130,000 individuals throughout a number of significant websites. At Los Alamos in New Mexico, the Military took control of 54,000 acres, a few of which was land where genealogical Pueblo had actually formerly lived for centuries. As well as although the Pueblo country participants might not access the land straight any longer, numerous remained to live near the website while the atomic bomb was being developed.

In 1944, the year prior to Aggie signed up with the job, amounts of plutonium huge sufficient to be seen by the nude eye were gathered on website for the building of the bomb. As the head of the Manhattan Task’s clinical group placed it, “The principal problem of the wellness team was the analysis of duplicated blood matters on subjected workers.”

One method of keeping track of for both severe as well as persistent radiation direct exposure is to search for decrease in the blood cells generated by the bone marrow– white blood cells, red cells, as well as platelets. That’s why keeping track of the researchers’ blood was so vital. As well as for that, they required specialists like Aggie.

Floy Agnes Lee: I needed to discover just how to take blood, just how to check out the blood cells, what sort of blood cell, as well as all that’s gotten in touch with the hematology.

Monica Lopez: Aggie was appointed to specific researchers. Among those researchers was the prominent Italian physicist Enrico Fermi.

Fermi led a team that was developing a speculative atomic power plant under the football area at the College of Chicago. The activator was called Chicago Stack 1. And also as you listened to in the previous episode, it existed that Fermi as well as his group produced the initial continual nuclear domino effect. In 1944, he ended up being an associate supervisor at Los Alamos as well as remained for greater than a year.

Due to the extremely categorized nature of the Manhattan Task, Aggie had no concept that Fermi was when he concerned Los Alamos.

Floy Agnes Lee: I just understood him as a number. As well as we reached chatting, as well as we hopped on the topic of tennis. So we would certainly play tennis.

This was prior to the bomb was gone down. Anyhow, after the bomb was gone down, the GI’s that operated at the research laboratory turned up as well as trembled my hand as well as claimed, “You were the individual that stuck the hand of the terrific Enrico Fermi.” I claimed, “What? “Yes, Enrico Fermi.”

We really did not recognize that we were working with the atomic bomb with the exception of the physicists. We assumed they were doing chemical war.

Monica Lopez: Yet they did recognize that the job they were doing threatened due to the fact that so little was understood about the results of radiation, as well as there had actually currently been one fatality from radiation direct exposure prior to Aggie began her job there.

Simply just how hazardous ended up being clear to Aggie in the results of a 2nd mishap with plutonium. It took place 9 months after completion of the battle as the study right into nuclear tools proceeded.

On the mid-day of Might 21st, 1946, a team of researchers was collected around a metal round in a laboratory at Los Alamos to observe an experiment. The objective was to create a plutonium core to create a brief regulated nuclear domino effect.

Among those researchers was Louis Slotin, a 35 year-old Canadian physicist that had actually executed numerous trying outs plutonium. Yet on this particular day, Slotin’s hand slid while running the experiment, creating a ruptured of radiation in the area.

Floy Agnes Lee: As well as Slotin was totally subjected.

Monica Lopez: Nearly instantly, among Slotin’s hands transformed a waxy blue as well as created huge sores. He had inner radiation burns. Aggie became part of a group that took his blood in the days that adhered to. His leukocyte matter dropped. He got on a coma. His body, Aggie remembered, began to swell.

Floy Agnes Lee: Slotin started to boost in dimension. As well as it was tough to take his blood. I lastly needed to take it from the ear.

His mom as well as daddy were called due to the fact that they understood he had not been gon na live. It was simply 9 days after the mishap, as well as his moms and dads came as well as stood in the entrance as well as searched in as well as saw him.

Certainly, the following day he passed away of radiation poisoning.

Monica Lopez: After the battle, Aggie proceeded operating at Los Alamos. At a celebration one evening, prior to Fermi went back to Chicago, he approached her.

Floy Agnes Lee: He came as well as rested with me as well as he claimed, as well as since the bomb has been gone down, what are you mosting likely to do? As well as I claimed, well, I wish to go as well as research even more concerning what radiation does to living cells.

He claimed, involve the College of Chicago.

Monica Lopez: Therefore she did.

Aggie started her PhD research studies in zoology at the College of Chicago in 1946, while likewise operating at the Metallurgical Lab, which would certainly end up being Argonne National Laboratory.

That was where she fulfilled– as well as quickly wed– fellow researcher Clyde Stroud. Yet when their child was simply 2 years of ages, Stroud passed away of cancer cells.

Yet Aggie was figured out to proceed her research studies.

Floy Agnes Lee: I chose I mosted likely to Chicago to obtain my PhD, as well as I’m gon na obtain it. It took me concerning 14 years to obtain the PhD, as well as I remained in my forties when I obtained it. Yet I did it.

Monica Lopez: Aggie’s rate of interest in the results of radiation on the body never ever subsided as well as ended up being main to her additional study. She investigated using radiation for dealing with cancer cells, she saw just how maybe utilized forever. As well as in the 1960’s while operating at the Jet Propulsion Lab, she originated a technique of evaluating chromosomes making use of an electron microscopic lense as well as a computer system the dimension of a big area.

In the 1970s, Aggie went back to Los Alamos, where everything began, to operate in the wellness lab as a radiobiologist. What inspired her was, partially, individual.

Floy Agnes Lee: I assume the most awful impact of Los Alamos, not simply on the Pueblo, yet the bordering location is the radiation that has actually triggered leukemia. I have 4 loved ones. 2 are my sis as well as my bro passed away of leukemia. 2 relatives have actually passed away of leukemia.

So there, I assume that the radiation has something to do with it, you recognize. I have no chance of confirming that. It’s simply a supposition of radiation misbehaves.

Monica Lopez: She relinquished Los Alamos aged 62.

Floy Agnes Lee: After I retired, I actually retired. I played tennis, I played golf.

Monica Lopez: Till her sight fell short.

Floy Agnes Lee: I needed to give up golf due to my sight. I could not see where the round went.

Monica Lopez: The meeting you have actually been listening to was carried out in 2017, when Aggie was 94. It occurred in Santa Fe, where she was living at the end of her life. It’s clear from the meeting that she had uncertainties concerning her very own wellness as well as the impact of having actually invested years analyzing living cells for radiation.

Floy Agnes Lee: I sense that possibly possibly the direct exposure to all that light originating from contaminated product as well as the light from the microscopic lense had something to aid create my loss of sight.

Aggie likewise made it clear because meeting from 6 years ago that although she was all as well knowledgeable about a nuclear tool’s harmful power, she really did not question that the atomic bomb needed to be developed– as well as utilized. As it ended up, that pivot at a very early age, from a desire for flying planes to the Manhattan Task, concerned specify the remainder of her life.

Dr. Floy Agnes Lee, figured out trainee as well as achieved study researcher, passed away on March 6, 2018 at the age of 95.

Interview with Floy Agnes Lee

Atomic Heritage Structure, Voices of the Manhattan Task

Meeting carried out February 6, 2017

Los Alamos Historical Document Retrieval and Assessment (LAHDRA) Project (Centers for Illness Control as well as Avoidance, 2018)

The CDC performed this job to review launches of products from Los Alamos National Lab that had the possible to create off-site carcinogen. Together with an independent service provider, the company methodically evaluated all readily available records associated with LANL procedures as well as recognized documents that add details concerning launches of chemicals as well as radionuclides from the website in between 1943 as well as 2010.

The Making From the Atomic Bomb by Richard Rhodes (Simon & & Schuster, 1986)

This publication covers individuals as well as occasions from very early 20th century explorations bring about the production of nuclear domino effect, via the Manhattan Task as well as the 1945 battles of Hiroshima as well as Nagasaki. This Pulitzer Reward winning publication is taken into consideration a basic authority on very early nuclear tools background.

“The Demon Core and the Strange Death of Louis Slotin” by Alex Wellerstein ( The New Yorker, 2016)

This short article states the unfortunate fatality of Louis Slotin at Los Alamos on Might 21, 1946. Slotin was showing a high-risk treatment called “pleasing the dragon’s tail,” entailing a nuclear tool core. Throughout the demo, a problem happened, as well as the core went important, giving off a ruptured of radioactivity that later on eliminated him.

This post from the Los Alamos Background Gallery offers scans as well as a records of Manhattan Task physicist Phil Morrison’s main letter reporting on the Slotin mishap. The article likewise includes Burt Sauer’s created story of the case, which brings the occasion right into dazzling quality.
