Jacob
F.
Bender

JACOB F. BENDER was born in Lancaster PA on April 28, 1892, one of the identical twin boys born to Charles E. and Ada Bender.  Charles Bender was a machinist by trade. The family had moved to Philadelphia by the time of the 1900 Census. When the Census was again taken in 1910, the Benders had moved to Camden NJ, and were living at 141 South 32nd Street in East Camden. Both Jacob and his brother Charles Walter Bender were working as draftsmen by that time. Charles E. Bender would reside at  141 South 32nd Street until the early 1920s. 

When the 1914 City Directory was published, Jacob Bender had married Linda Kessler and was living with his parents and his wife at 141 South 32nd Street. By 1917 the Benders had two children, and were living at 9 Leonard Avenue in East Camden. 

When he registered for the draft on June 5, 1917,  Jacob Bender was working as a marine engine draftsman at the New York Shipbuilding Corporation shipyards. He had by that time served for four years in the New Jersey National Guard as a a sergeant in the 4th Infantry Regiment. He was not inducted into the Army, however, most likely because his work at the shipyard was deemed vital to the war effort.

By 1920 Jacob F. Bender and his wife Linda were living at 146 South 32nd Street. When the Census was taken in April of 1930, the Bender family, which by now included three children, Edward, Robert and Ada, was still at 146 South 32nd Street in East Camden. By this time Jacob Bender was working for RCA Victor in Camden. His widowed father also resided with the family. 

Jacob Bender later worked as an engineer at RCA and was instrumental in the commercial development of the electron microscope in the 1940s under Vladimir Zworykin and Charles Hillier. 

The Bender family had moved around the corner to 3175 Fremont Street by 1947. Jacob Bender is not listed in the 1956 New Jersey Bell Telephone Directory.

Jacob F. Bender passed away in Philadelphia PA on July 5, 1967.
