Inasmuch as our (optically) inactive material subjected to characteristic reactions of eserethole of natural origin yielded perfectly analogous results, we expressed the belief that our product was the real d,l-eserethole and that of the English chemists must be assigned another constitution.

“This is now proved conclusively by synthesis of l-eserethole, identical with the product of natural origin.”

Following the total synthesis of physostigmine and the separation of physostigmine into its optical isomers, Julian was to make another discovery at DePauw that not only would enhance his stature as a chemist but also greatly improve the lives of many.

led to the successful synthesis of d,l-eserethole.

“To our surprise, our d,l-eserethole exhibited entirely different properties than those of a compound synthesized by Robinson and his coworkers and called d,l-eserethole. Ultimately, he obtained a position at Glidden Company as the lab director. Despite the fact that many residents of the town relied upon his methods to relieve their pains of and provide for their safety, some still would not accept him because of his race.

In 1954, Julian left the Glidden Company to establish Julian Laboratories which specialized in producing his synthetic cortisone.

He soon left Howard and moved back to DePauw where he was appointed a Research Fellow in Chemistry. degree. Subsequent modification of this "accidental procedure" led to the daily production of 100 pounds of mixed soya sterols worth more than $3.6 million annually. In the meantime, the first of a series of ten papers dealing with the synthesis of physostigmine, by Robinson and his collaborators, appeared and seemingly proved convincingly that the (course) suggested in our formulas could not be realized in practice.

He left West Virginia and served as an associate professor of chemistry at Howard University in Washington, D.C. for two years.

In 1929, Julian received a Fellowship from the General Education Board and traveled to Vienna, Austria in pursuit of a Ph.D. He sold the company in 1961, becoming one of the first Black millionaires, before founding Julian Research Institute, a nonprofit organization that he ran for the rest of his life.

He died of liver cancer on April 19, 1975.

Recognition

In 1973, Julian became the first Black chemist elected to the National Academy of the Sciences.

Our experiments, nevertheless, were continued and ...

In spite of this challenging beginning, he graduated first in his class, with Phi Beta Kappa honors.

Life in Academia

After college, Julian accepted a position as a chemistry instructor at Fisk University. He developed efficient syntheses for whole families of steroids including 4,5-epoxy steroids, 16,17-epoxy steroids, 21- iodo steroids, 17-hydroxy steroids, 4-halo steroids, and numerous steroids containing the diosphenol structure.

At DePauw, he worked with an associate of his from Vienna, Dr. Josef Pikl, on the synthesis of physostigmine, a drug which was used as a treatment for glaucoma. Upon graduation in 1916, Julian applied to and was accepted into DePauw University in Greencastle, Indiana. Percy continued his success as he next developed a way to inexpensively develop male and female hormones from soy beans.

The Glidden Company was a leading manufacturer of paint and varnish and was counting on Julian to develop compounds from soy based products which could be used to make paints and other products. After two years at Fisk, Julian was awarded the Austin Fellowship in Chemistry and moved to the distinguished Harvard University in Cambridge, Massachusetts.

With his doctorate in hand, he returned to DePauw to continue his research.
