About us



Egyptian BuildingThe Department of Pharmacology and Toxicology at VCU has a long and distinguished history. In 1838, the department was created at the inception of the Medical College of Virginia when Dr. Lewis Webb Chamberlayne was appointed Chairman of the Department of Materia Medica and Therapeutics. Upon Chamberlayne’s death in 1854, Dr. Beverly Randolph Wellford took over the department until 1868. His son, Dr. John Spotswood Wellford, succeeded him and served the department until 1881.

Francis W. Upshur

In 1897 the Medical College was divided into separate units of Medicine, Dentistry and Pharmacy, which later became three schools or colleges. In the early years of the 20th century, the department’s faculty grew from a single professor to four when the chair, Francis W. Upshur, hired Dr. C.C. Haskell and two adjunct faculty members.

Dr. C.C. Haskell: 1915 to 1936

In 1915, Dr. Haskell became chair of the combined departments of Physiology and Pharmacology. He hired Dr. Harvey B. Haag as a part-time assistant in the department while he was completing medical school. 

Dr. Harvey B. HaagDr. Harvey B. Haag : 1936 to 1955

After a year as a postdoctoral fellow at Cornell, Dr. Haag returned to MCV as assistant professor of physiology and pharmacology. From 1936 until his semi-retirement in 1955, Dr. Haag was chair of the Department of Physiology and Pharmacology and, from 1947 to 1950, concurrently dean of the School of Medicine. He was the first individual to introduce a research base in pharmacology and toxicology at MCV.

In addition to his contributions to teaching and research, Dr. Haag served on many national committees, councils and boards. He was elected secretary and president of the American Society for Pharmacology and Experimental Therapeutics in recognition of his many contributions to the field. At the height of Haag’s tenure as chair, the pharmacology faculty consisted of Drs. Haag, Larson, Helen Ramsey, Finnegan and Pennschmidt, and Dr. R.B. Smith, who later became dean of the School of Pharmacy and president of MCV.

It was during this period that the graduate program in pharmacology was initiated. The first student was Jack K. Finnegan, who was enrolled at the University of California but carried out the major portion of his research at MCV, under the direction of Haag. He received his degree from California in 1945 and was immediately added to the faculty at MCV.

Upon Dr. Haag’s death his family and friends created the Harvey B. Haag Professorship, currently occupied by Dr. Louis Harris.

Dr. Paul S. LarsonDr. Paul S. Larson: 1955 to 1972

In 1955, Dr. Paul S. Larson became the thirteenth chair of the Department of Pharmacology. This coincided with the completion of the McGuire Hall Annex and the physical consolidation of the department into McGuire Hall and its annex. Prior to this, the department was geographically distributed in a number of buildings, a problem to which the current department can relate.

Dr. Larson was the first chair of MCV's Department of Pharmacology with an academic degree (Ph.D.). All previous chairs held professional degrees in medicine. Larson was the first Haag Professor and a distinguished scholar whose work in toxicology and nicotine pharmacology brought national and international recognition to the department. His publications provided an outstanding contribution to the knowledge base concerning this drug. Dr. Larson was one of the founding members of the Society of Toxicology and served as its president from 1963-64. At the time of his retirement, the department consisted of 11 full-time faculty members and eight adjunct appointments, including Daniel T. Watts (dean of the School of Basic Sciences) and Dr. Lauren Woods (vice president for health sciences). There were three research associates or postdoctoral fellows and six graduate students. It also was during his tenure that the Medical College of Virginia was combined with the Richmond Professional Institute to form VCU.

Dr. Louis HarrisDr. Louis Harris: 1972 to 1992

In 1972, Dr. Louis S. Harris assumed the post as chair of the Department of Pharmacology on a part-time basis, until his final move from Chapel Hill, N.C. in 1973. Through his endeavors the department was able to expand the faculty and research space. In 1983, the name of the department was changed to the Department of Pharmacology and Toxicology, to recognize the growing strength and importance of toxicology in the program. The graduate program was greatly expanded during this time and remains of great interest to Dr. Harris.

Dr. George KunosDr. George Kunos: 1992 to 2000

In 1992, Dr. George Kunos assumed the post of chair of the Department of Pharmacology and Toxicology. It was during this period that the department joined the School of Medicine. During his tenure the research component of the department was strengthened with greater diversity in the three principal areas of drug abuse, toxicology and molecular biology. Studies in his laboratory examined the role of endocannabinoids in neuroendocrine, metabolic and cardiovascular regulation. Dr. Kunos is the current Intramural Director of the National Institute on Alcohol Abuse and Alcoholism (NIAAA) of the National Institutes of Health.

Dr. Billy R. MartinDr. Billy R. Martin: 2000 to 2008

Dr. Billy Martin assumed the post of chair as the department entered the new millennium. He played a prominent role in developing the department’s reputation for landmark research in drugs of abuse. For more than 30 years, his primary focus was researching the effects of marijuana’s principal psychoactive ingredient, delta-9-tetrahydrocannabinol, or THC. Dr. Martin also made significant contributions to our understanding of the actions of nicotine. Both his work on cannabinoids and nicotine have lead to potential therapeutic agents currently under development.

Dr. Billy R. MartinDr. William L. Dewey: 2008 to current

Dr. William Dewey assumed the post of chair of the department and continues in a long line research of drugs of abuse. He is responsible for a large body of research which have contributed significantly to our understanding of the mechanism of action of opioids and cannabinoids. He is the originator and director of the longest, continuous National Institute on Drug Abuse training grant in the USA (1976-ongoing).  Thanks to a first-rate and energetic faculty, the department has grown to its present status — one of the finest pharmacology and toxicology departments in the world.
