Max Factor, Sr., Polish-born American make-up artist and businessman, founded the Max Factor Company (b. 1877)

Maksymilian Faktorowicz (September 15, 1877 – August 30, 1938), also known as Max Factor Sr., was a Polish-American businessman, beautician, entrepreneur and inventor. As a founder of the cosmetics giant Max Factor & Company, he largely developed the modern cosmetics industry in the United States and popularised the term "make-up" in noun form based on the verb.

He is also known for doing makeovers for starlets and giving them their signature looks; his most iconic works include Jean Harlow's platinum hair, Clara Bow's bob, Lucille Ball's false lashes and red curls, and Joan Crawford's "Hunter's Bow", or overdrawn lips.
