Charlotte ('Lotti') van der Gaag (The Hague, 1923 - Nieuwegein, 1999) was a well-known sculptress, ceramist and painter. In the 1940s she took classes at the Royal Academy of Art and the Free Academy in The Hague. In 1950 Lotti moved to Paris and came into contact with members of the Cobra movement. She was unofficially — and the only woman — part of that movement, something firmly denied by some of that group. Her work was heavily influenced by the Cobra group, especially when it came to her fantasy characters. In 1951 she took some lessons in the studio of Ossip Zadkine. The Stedelijk Museum in Amsterdam showed her work in 1952 and afterwards she also got exhibitions abroad. In 1958 she received the Jacob Maris Prize and in 1993 the Ouborg Prize.
