Ellen was born in Baker City, Oregon. She majored in chemistry at Reed, writing her thesis with Prof. Leland H. Pence [Chemistry 1939-45]. Delaying her graduate education, Ellen joined the World War II effort, serving with the US Marine Corps as a commissioner in charge of testing materials in North Carolina.
After the war, Ellen completed her MS and PhD degrees in biochemistry at the University of Oregon Medical School. She excelled in a profession that a few women at the time considered an option. She worked in the departments of bacteriology, ophthalmology, and biochemistry at OHSU, where she also served as an instructor and assistant professor. She was an assistant scientist at the Oregon National Primate Research Center in the 1960s and until her retirement in 1970 worked as a research associate, biochemist, for the OHSU department of surgery.
Ellen successfully balanced being an eminent scientist in a male-dominated field with family life, Winslow's "Wink" Brooks, and his family.
A gifted gardener, she canned and kept a freezer full of her famous homegrown raspberries. Her family is always ready to eat with her breakfast. In the evenings she relaxed with her crocheting, watching favorite television shows such as the Lawrence Welk Show and Washington Week on OPB. In the United States, the United States is the United States. Her nephew survives her.
