John A. Biberdorf, an aerospace engineer who was part of a team that developed early space satellites, maker of prize-winning pickles, lover of dogs and ducks, military historian, and resident of Los Altos for 56 years, died on Sept. 17 at age 92. John was born on Nov. 20, 1926 in Kampeska, South Dakota to Ernestine (Hine) Biberdorf and Arthur C. Biberdorf, who both immigrated from Ukraine in the late 1800s. Family lore says John, the seventh of eight children, was born on a sled on the way to the doctor. John was preceded in death by his three sisters and four brothers. He is survived by his two daughters, Ann Sibbet (husband John Sibbet) of Sacramento and Jean Biberdorf of San Jose, and his wife of 66 years, Vinnie Biberdorf of Los Altos. Not a fan of work on the farm, John taught himself radio repair from a correspondence course as a teen, which landed him a job off the farm and set his career in motion. In 1945, at the age of 18 he joined the Navy, which furthered his training in electronics and communications.
