In 1937, Beach was employed by the
American Museum of Natural History in
New York City. In 1950, he accepted a position as a Sterling Professor of Psychology. A sabbatical at the
Center for Advanced Study in the Behavioral Sciences at
Stanford began in 1957–58. In 1958, Beach accepted a position as Professor of Psychology at the
University of California, Berkeley. The research program on dogs that was initiated at Yale was expanded at Berkeley. Beach helped found the
Field Station for Behavioral Research near the Berkeley campus. Beach was known for being an excellent mentor to graduate students while at Berkeley. Beach became
professor emeritus in 1978, but still remained active in his work. Beach was awarded the APA award for Distinguished Teaching in Biopsychology in 1986. Beach, along with
anthropologist Clellan S. Ford, co-authored the book
Patterns of Sexual Behavior (1951), considered a "classic" of its field. He was elected a Fellow of the
American Academy of Arts and Sciences in 1953 and a member of the
American Philosophical Society in 1961. He also authored an edited version,
Human Sexuality in Four Perspectives, in 1977. Beach's second wife, Anna, died in 1971, and he thereafter married Noel Gaustad. In the days prior to his death, Beach continued his work from a hospital bed, reading scientific literature and giving advice about a paper on
reproductive behavior to be presented at an
Omaha conference on June 12, 1988. He died on June 15, 1988. Beach's work in
comparative psychology was expansive and influential. Beach studied behavior in rats, dogs, cats, quail, pigeons, dolphins, and hamsters. Beach was particularly interested in the role of
endocrinology in behavior. He studied the effects of
endocrines on behaviors through methods such as castration, isolation, brain legions, and hormone manipulation. Other behaviors that Beach was interested in include instinct behavior, maternal behavior, and menstruation. ==Legacy==
