Sidney Factor, who helped build Max Factor & Co., the cosmetics company his father founded, into an internationally known name, died Thursday at his home in Beverly Hills. He was 89.

Factor learned the family business at a young age by working after school with his father, Max Factor Sr., who launched the business in St. Louis at the World’s Fair of 1904. At first, the company specialized in wigs, rouge, and face creams. After relocating to Los Angeles several years later, Factor added a line of professional makeup for motion pictures in 1914.

In 1928, the company moved into the Art Deco building in Hollywood that is now a Los Angeles historic landmark and home of the Hollywood Museum. The products were manufactured on the upper floors of the building while the lower floors contained makeup salons.

The array of cosmetics grew to include false eyelashes and other items originally created for Factor’s movie clientele.

Sidney Factor joined the business in 1936. Through the 1950s he helped expand it into Canada, Australia, Japan, Latin America, and South America.

When he retired in 1962 as executive vice president in charge of international markets, his division led the company in sales. The Factor family sold the business in 1973, and it was acquired later by Procter & Gamble, which still owns it.

Factor went on to establish his own business, Sidney Factor Enterprises, to breed and race thoroughbred horses.

Born in 1916 in Los Angeles, Factor was one of seven children, several of whom went into the family business.

A graduate of Beverly Hills High School and the University of Southern California, Factor was an accomplished athlete from a young age who won tennis tournaments starting in high school and later took up golf, winning more than 100 amateur trophies.
