Lee De Forest was born August 26, 1873 in Council Bluffs, Iowa, the son of Henry Swift De Forest and Anna Margaret Robbins.

He is a direct descendant of Desforetz-3 the leader of a group of Walloon Huguenots who fled Europe in the 17th Century due to religious persecution.

Lee De Forest boasted that he'd made and lost four fortunes.

Census of 1920 shows Lee and Mary Mayo in the Bronx, with their child Eleanor (or Elnora) De Forest, born just the previous year.

In Census of 1940, he and Marie M. share the household alone in Los Angeles, California.

He died in Hollywood on June 30, 1961, aged 87, relatively poor, with $1,250 in his bank account.
