91亚色传媒

Donald David Brown, a pioneer in molecular embryology and a member of the 91亚色传媒 for almost 60 years, died in Baltimore County, Maryland, on May 31. He was 91.

Brown was born in Cincinnati, Ohio on Dec. 30, 1931 to Albert Brown, a ophthalmologist and retina surgeon, and Louise Rauh. After graduating from Dartmouth College in three years, Brown earned his master’s and medical degrees at the University of Chicago.  He worked as a postdoctoral fellow with biochemist and future Nobel laureate Jacques Monod at the Pasteur Institute in Paris.

On his return to the U.S., Brown joined the Department of Embryology at the Carnegie Institution of Washington in Baltimore. He worked there for the remainder of his career, becoming a department director 1976 and retiring as an emeritus scientist in 2005.

The journal dubbed Brown the father of molecular embryology. Curious about embryonic development, he helped moved the field from theoretical work to test-tube elucidation of the molecular changes in embryos. His , according to Carnegie Science, helped expand knowledge of genes and paved the way for early genetic engineering. He authored more than 220 studies.

Eric D. Isaacs, Carnegie’s president, paid tribute to Brown’s research and his role in training younger researchers, both at Carnegie and at the Life Sciences Research Foundation, which he founded in 1981 to support postdoctoral researchers. 

“Don was an exceptional scientist and a thoughtful mentor to generations of biologists,” Isaacs said in a . “Don Brown’s work transformed humanity’s understanding of molecular biology, and every day his research informs new discoveries about the nature of life.”

Another Carnegie colleague praised Brown for his emphasis on impactful research. “He told people, ‘Life is too short to try to do all your ideas — do your best ones, the ones that could have the biggest effect in science,’” Allan Spradling told the .

One mentee lauded the late researcher’s professional integrity. “I treasured Don Brown's belief that life is too short to make two papers out of one,” said Nina Fedoroff, a National Medal of Science winner who worked with Brown at Carnegie early in her career.

Brown shared the 2012 Lasker–Koshland Special Achievement Award in Medical Science. The Society for Developmental Biology gave him its 2009 Developmental Biology–SDB Lifetime Achievement Award. He received many awards and honors in his long career.

Outside the laboratory, Brown enjoyed fly-fishing and tennis, his wife of 65 years, Linda Weil Brown, told the Baltimore Sun.

Brown is also survived by his children, Deborah Brown and husband David Isaac, Christopher Brown and wife Gina Brown, and Sharon Burris-Brown and husband Dave Burris–Brown; his sister-in-law, Marian Brown; six grandchildren and five great-grandchildren.
