Of Chinese descent, Leong Pang was born in Princes Town and sent to school in China; she is known to have painted while there.
In 1929 she was among the founders of the Society of Trinidad Independents; other members included C. L. R. James, Alfred Mendes, Albert Gomes, Ivy Achoy, and Hugh Stollmeyer,[1] with whom she would go on to develop a close working relationship.
[2] The group met in private homes to paint and discuss ideas, but was condemned for being bohemian and disbanded in 1938.
[1] Leong Pang was intensely private, but continued to be supportive of other local artists until her death; Boscoe Holder and Carlisle Chang are among those whose works she influenced,[1] as well as Althea McNish.
She married the archaeologist John Albert Bullbrook, but it was said to be a lavender marriage, as both were homosexual.
