Which Polish-American businesswoman founded her namesake cosmetics company in 1902? Helena Rubinstein founded Helena Rubinstein Incorporated in 1902.

Born Chaja Rubinstein in Kraków, then part of Austria-Hungary, she emigrated to Australia after refusing an arranged marriage. There, women noticed her unusually smooth complexion and asked about the cream she used. Rubinstein began selling the preparation, later known as Crème Valaze, and opened a salon, laboratory, and boutique in Melbourne in 1902.

Her business expanded from Australia to London in 1908, Paris in 1912, and New York in 1915. Rubinstein combined cosmetics with consultations and salon treatments, helping popularize the idea that skin should be assessed by type and treated with specialized products. She also promoted beauty care as a field connected to science, even when some of the era's claims were exaggerated.

Rubinstein became a lifelong rival of Elizabeth Arden, another major beauty entrepreneur. That rivalry explains a common quiz mistake: both women built influential cosmetics empires, but only Rubinstein founded the company carrying the name Helena Rubinstein.
