Eugene Greider was born in New York. He finished a three-year pre-med course but ran out of money. He joined the U.S. Navy and flew PBYs and R4Ds during World War II. After the war, he still needed money to pay for his medical education, so he joined Seaboard in 1947 as one of the first pilots and spent several years flying and attending New York Medical College.
He graduated from New York Medical College in 1952 and moved to California and opened a family practice in Sunnyvale. Later he was a founder of El Camino Hospital in Mountain View.
Dr. Eugene Greider was survived by his wife Norma, children Cheryl Bradkin of Whidbey Island, Wash., Brett Greider of Santa Clara, Buff Greider, M.D. of Los Altos, Laurey Greider Carter of San Rafael, and six grandchildren.
