The Horace Albert Barker Collection, 1930-1997, consists primarily of materials
documenting Barker's long career in the field of Microbiology at the University of California, Berkeley. The
bulk of the collection consists of research notes and reports on Barker's innovative experiments. The collection
also contains a considerable amount of correspondence, notes for lectures, seminars and courses, administrative
information from UC Berkeley departments, and limited amounts of personal materials. The collection has been
divided into six series: Correspondence, Lectures and Seminars, UC Berkeley, Research, Professional
Associations, and Personal Papers.
Horace Albert Barker was one of the most important microbiologists of the 20th century. During his career he
contributed to several breakthroughs in the areas of oxidative assimilation by bacteria, the biological
formation of methane, the carbon dioxide utilization of heterotrophic bacteria, the synthesis and degradation of
lower fatty acids, and the fermentations of amino acids and purines. He was a member of the team that, in 1944,
discovered the enzymatic steps that living cells take when they synthesize sucrose, and his work with the
coenzyme B-12 earned him a nomination for the Nobel Prize in 1975.
