In Memoriam: Dr. Roscoe Brady

rbrady-240x300

Roscoe Brady, MD, PhD (10/11/1923-6/13/2016), is the technical co-founder of American Gene Technologies™ (AGT). Dr. Brady was both a brilliant physician and an accomplished research scientist, having spent more than 50 years researching hereditary metabolic storage diseases (also known as lipid or lysosomal storage disorders).

Dr. Brady is probably best known for having co-discovered the enzymatic defects in Gaucher disease, which subsequently led to his development of a successful enzyme replacement therapy (ERT). According to the National Institute of Neurological Disorders and Stroke (NINDS), “His work has defined much of what is known about the biochemistry, enzymatic bases, and metabolic defects of these disorders, and he has inspired colleagues throughout the world to define the causes of many other related disorders and to pursue further investigations in this field”.

HISTORY

Dr. Brady was born in Philadelphia, PA in 1923 where he later attended Pennsylvania State University. He went on to earn his medical degree from Harvard Medical School in 1947 and interned at the Hospital of the University of Pennsylvania.

Upon finishing his internship, Dr. Brady became a national research council fellow and then a US Public Health Service special fellow in the Department of Biochemistry at the University of Pennsylvania School of Medicine. It was there that he worked with biochemist Dr. Samuel Gurin researching the biosynthesis of testosterone, fatty acids, and cholesterol using radioactive isotopes. His early work in this area inspired Dr. Brady’s interest in lipid storage diseases.

CAREER & ACCOMPLISHMENTS

Dr. Brady joined NINDS in 1954 as Chief of the Section on Lipid Chemistry in the Laboratory of Neurochemistry, and later became Chief of the Developmental and Metabolic Neurology Branch. Dr. Brady would remain at NINDS for his entire career, and it was here that he discovered the missing enzyme that causes Gaucher disease and other metabolic disorders.  Dr. Brady developed an enzyme replacement therapy, first reported in 1973, and was in widespread use by 1991 as the first effective treatment for Gaucher disease.

AWARDS

Dr. Brady is the recipient of many professional awards including:

 

  • Gairdner International Award
  • Cotzias Award from the American Academy of Neurology
  • Pasano Foundation Award
  • Lasker Foundation Clinical Medical Research Award
  • Kovalenko Medal from the National Academy of Sciences USA
  • United States National Medal of Technology and Innovation
  • Pollin Prize for Pediatric Research

Dr. Brady’s enzyme replacement therapy has become a model for other inherited enzymatic disease treatments.
