Dr. Percy Julian 1899-1975


It is hard to imagine in this modern age having the restrictions that so many felt under Jim Crow.  It wasn’t fair and it wasn’t right, but at the time it was the reality.  Imagine being an intelligent young man who wants to see how things work and only be allowed to attend school until 8th grade and then told that’s it.  This is what happened to Dr. Percy Julian.  He was born in Montgomery, Alabama on April 11, 1899, the son of a railway clerk and grandson of slaves he grew up and grew beyond the restrictions his era held for African Americans.  Thanks to an insatiable desire to succeed he made history and went on to provide a way for many of our modern medicinal needs.

In 1920, Percy Julian graduated from DePauw University in Greencastle, Indiana serving as the class Valedictorian.  Given the 8th grade education he acquired, this feat alone is amazing.  He received the prestigious Austin Fellowship from Harvard University as well, this made his determination all the more amazing.  He spent several years teaching primarily at African American universities such as Howard and West Virginia State College.  For an African American, and although he more than qualified, he was often passed over for professorships and private sector positions.  Travelling to Austria, Dr. Julian received his doctorate from the University of Vienna in Chemistry of Medicinal Plants where he met Josef Pikl. 

Drs. Julian and Pikl worked together creating the first total synthesis of physostigmine, which is used to treat glaucoma and is found in the Calabar bean.  It was extremely expensive to try and extract certain substances such as hormones and steroids from animals tissues.  The task of finding a way to mimic these same or similar substances from plants would be revolutionary, allowing for easier extractions, production and in the end making these medication available to the masses as a more affordable cost. 

After working for several years teaching at the universities, he accepted a position at Glidden Company in their Soya Division.  He was the head of research.  During his tenure there a vat of soy oil was contaminated by water, when it was brought to his attention he identified the white growth as being stigmasterol, which is used to produce the hormone progesterone.  For those who don’t know, progesterone is a female sex hormone, it is necessary to ensure pregnancy and to maintain pregnancy in women.  This accidental contamination revolutionized the way progesterone would be produced.  The problem wasn’t that the hormone couldn’t be reproduced, it could and easily, but there was no way to mass produce the hormone.  Dr. Julian developed the innovative process of extraction and was able to produce 5 to 6 pounds of progesterone daily.  This process led to the later synthesis of cortisone and testosterone as well as a bunch of other hormones and steroids that make living a little bit easier for people. 

He paved the way to make medications that were cost prohibitive to make and even more so for people to purchase, more readily available.  I imagine suffering with the pain and discomfort of arthritis, which I do, and having no access to anti-inflammatory and corticosteroids for reliefs.  Thanks to this man and his colleagues we have these treatments and they are affordable.  His work provided the foundation for chemical birth control and immune suppressant drugs.  He applied for and held hundreds of patents. 

Although so much of his most notable work was in plant chemistry he did develop a soy based foam Aero-Foam that was able to douse oil and gas fires.  This was quickly picked up for use by the military.   He and his family were also the first African Americans to own a home in Oak Park, Illinois.  Initially, his reception wasn’t welcoming and his house was fire bombed twice, but now the town celebrates his birthday, adopting him as a hometown here. 

Although Dr. Julian has more accomplishments and was part of important work in the medicinal and organic chemistry fields he was also a humanitarian working hard to try and help give disadvantaged populations a helping hand.  He sat on the boards of several notable organization and universities, he also contributed to the NAACP legal and economic funds. 

His death on April 19, 1975 was a great loss not only to the scientific community but to society as a whole.
