Alexander Glazer, a renowned biochemist and environmentalist, died July 18. He was 86.

Alexander Glazer

Glazer was born in Poland on July 7, 1935, and immigrated to Australia with his mother after World War II. He earned both his bachelor’s and master’s degrees in biochemistry from the University of Sydney, where he also met Eva Warner who he married in 1958. 

While working toward his master’s degree, Glazer attended a lecture given by biochemist from the University of Utah. Inspired by the research and the Southwest’s landscape, Glazer moved to Utah for his doctoral degree and researched the physiochemical properties of proteins under Smith until 1960. 

Glazer continued to navigate the globe for his postdoctoral work. He completed postdoctoral fellowships at the Weizmann Institute of Science in Israel and under at the Medical Research Council Laboratory of Molecular Biology in England. His former thesis advisor Smith recruited him to UCLA as faculty in 1964 and he subsequently moved to the University of California, Berkeley in 1976.

Much of Glazer’s early research focused on chemical modifications of proteins and the properties of enzymes including proteases and hydrolyses. With collaborators, he helped determine the structure of phycobiliproteins — light-harvesting structures found in photosynthetic cyanobacteria and certain algae. Through these studies, they were able describe how light energy is transferred to the reaction center in the cell. Glazer then demonstrated how these proteins could be used as fluorescent tags, which are now used to mark and sort living cells in the laboratory.

Glazer also recognized the advantage of what became known as “big data” and worked with statistician Peter Bickel to explore amino acid sequence conservation within protein families and understand how it relates to protein structure and function using publicly available protein sequence databases. Glazer retired from research in 1994 but continued to serve as co-chair of the department of molecular and cell biology at UC Berkeley and as a professor in the graduate school until 1997.

Glazer’s career took a turn when he was hired as the director of the University of California Natural Reserve System, which encompasses a network of field stations and protected natural lands. As director, he focused on pressing issues of environmental science such as nitrogen fixation, contamination of freshwater sources and the repercussions of oil production and use. He served as the system’s director for 11 years.

Glazer received numerous awards and honors throughout his career, including two Guggenheim fellowships, the Endeavor Prize from the British Association for the Advancement of Science, and election to the American Academy of Arts and Sciences and the National Academy of Sciences. 

According to an , Glazer enjoyed hiking and camping with his family in his free time, with favorite sites including the Lassen Volcanic Natural Park and the red rock country of southwestern Utah. He picked up natural photography as a hobby as well.

Glazer is survived by his wife, Eva; daughter, Judy; son, John; their spouses, Brian and Nandita; and four grandchildren.
