Gertrude Käsebier (born Stanton; May 18, 1852 – October 12, 1934) was an American photographer.
In July 1899, Alfred Stieglitz published five of Käsebier's photographs in Camera Notes, declaring her "beyond dispute, the leading artistic portrait photographer of the day". That same year her print of 'The Manger' (1900) National Gallery of Art sold for $100, the most ever paid for a photograph at that time.
Käsebier began to attend art school at the age of 37, a time when most women of her day were well-settled in their social positions. Käsebier never indicated what motivated her to study art, but she devoted herself to it wholeheartedly. She became known for her images of motherhood, her portraits of Native Americans, and her promotion of photography as a career for women.
