Robert Augustus Chesebrough, (January 9, 1837 – September 8, 1933) was an American chemist. 

He discovered petroleum jelly which he marketed as Vaseline and he founded the Chesebrough Manufacturing Company.

He was such a firm believer in its medicinal properties that he claimed to have eaten a spoonful of it a day.

During a bout of pleurisy in his 50s, he ordered his nurse to cover him from head to toe in the substance, and soon recovered.
