Robert Lincoln McNeil Jr. (July 13, 1915 – May 20, 2010) was an American chemist and pharmaceutical industry executive.

[1] After completing college in 1938, he joined McNeil Laboratories full-time, coming on board to what had been the family business for three generations having been founded in 1879.

[1] The company had been founded as a corner drug store and had grown into selling medicines on a commercial basis.

[1] To compete with the aspirin products sold by his company's competitors and having heard of work being done on the chemical by researchers, McNeil started in 1951 pursuing the development of what he named "acetaminophen", a chemical that had been discovered decades earlier but was little tested at the time as a pain reliever.

[8] McNeil also created the Barra Foundation, dedicating to helping non-profits to improve life in the greater Philadelphia area.
