He was best known for his success in business, notably the international beauty company he built with his mother, Estée Lauder. He was also an influential art patron.

Mr. Lauder, son of beauty entrepreneur Estée Lauder, played a pivotal role in transforming the company from one beauty brand into a leading conglomerate.

Leonard A. Lauder, who was known as much for his philanthropy and arts patronage as he was for his family’s beauty company, died Saturday at age 92.
