Forgotten is a 1933 American pre-Code film directed by Richard Thorpe.
Retired Papa Strauss, a widower, who has been a successful dye manufacturer, is being shifted around from one married son's home to the other, and is not welcome at all because his daughters-in-law object to his smelly pipe smoking.
Finally the family tucks him 'out of sight and out of mind' into a nursing home, with very little 'honor thy father' thought given to it.
However, unmarried daughter, Lena, who loves her father dearly— with help from an inheritance from her uncle, and her chemist fiancée, who has new patented technology — sets up a new dye works with her father as head.
The sons and their wives attitudes finally change.
