Armstead Otey Grubb (March 14, 1903 – December 5, 1968) was an American educator who served as professor of French and Spanish and as head librarian at Lincoln University in Oxford, Pennsylvania.

"[6] Grubb taught French for ten years at the William Penn Charter School in Philadelphia before joining Lincoln University's faculty as a professor of modern languages in 1937.

[1][5] Starting in 1940, Grubb served as registrar and head librarian, overseeing Vail Memorial Library's collections and staff.

[2] The next morning (Friday, December 6), Wilson and Cole searched the area and discovered Grubb's body in the basement of the vacant house at approximately 8:30 am.

[1] According to the coroner, Grubb had died within two or three minutes of the assault, suffering from a fractured skull and acute brain injury.

[1][2] Police arrested three local youths within hours and charged two with murder, robbery, burglary, and pointing a deadly weapon.

The suspects' father, farmer Earl Twyman, told The Philadelphia Inquirer that this gift reflected Grubb's customary generosity.

[1] In December 1968, the 15-year-old suspect, Gary Butcher, was convicted of voluntary manslaughter and conspiracy in a jury trial and was sentenced to six to twelve years in prison.
