Alan Hofmann

Alan Frederick Hofmann (May 17, 1931 – September 7, 2021) was a gastrointestinal physiologist, biochemist and clinician who was notable for his extensive basic, translational and clinical research on

Hofmann reviewed his 50-year research career up to 2009.[3] He made many advances in the chemistry and biology of bile acids, helping understand and treat various liver, biliary and digestive diseases.^[4][2]

His research includes many aspects of

He was instrumental in the development and evaluation of the use of bile acid therapy to dissolve cholesterol gallstones, first using chenodeoxycholic acid.^[9][10]

He published fundamental work on the

He has numerous scientific publications dating from 1960 to 2021. His initial publications in 1960 characterized his future research: Exchange of iodine-131-labeled chylomicron protein in vitro in the American Journal of Physiology [14] and the next (also a sole author publication) was in Nature on Micellar solubilization of fatty acids and monoglycerides by bile salt solutions.^[15]

He published over 500 articles, including original research and many invited contributions and reviews. His most highly cited publications are on the liver bile salt export pump (over 1100),^[16] the first description of gallstone dissolution by bile acid therapy (over 800),^[9] on the properties of bile salts (over 700),^[17] and the mechanisms whereby bile acids produce secretion in the colon (over 500).^[18] His articles have been widely cited, with an H-index of 111.^[19]

He received many awards recognizing his achievements, including honorary degrees and visiting lectureships.

Influence

Many leading physicians and investigators have cited the benefits of his influence and mentorship.^[2] These include Ian Gilmore^[20] and Aldo Roda.^[21] Together with Gustav Paumgartner in 1972, he helped establish the biennial series of international meetings on bile acids, sponsored by Dr. Herbert Falk and the Falk Foundation.^[22] These have been key in bringing together bile acid researchers and advancing knowledge of their actions and therapeutic value.^[5]

He endowed an annual lectureship at the Johns Hopkins University Gastrointestinal Division in 2005 as he was grateful to Hopkins for providing him with the scholarships which allowed him to attend college and medical school. This lecture has become the highpoint of the academic year, inviting a major GI scientist who is a role model as an academic investigator for faculty and fellows.^[23] Recipients have included James Boyer, Tachi Yamada, Monty Bissell, Jeff Gordon, and Anna Mae Diehl.

Personal

He lived in La Jolla California and was married for 43 years to the artist Heli Hofmann.^[24] He is survived by two children from his first marriage, Anthea Phillips and Cecilia McKenzie, five grandchildren, and two stepdaughters. He remained scientifically active into his 90th year, but suffered from multiple system atrophy. He died peacefully at home in La Jolla on September 7, 2021.^[25]
