David Saul Marshall (né Mashal; 12 March 1908 – 12 December 1995) was a Singaporean lawyer, politician, and diplomat who served as the first chief minister of Singapore from April 1955 to June 1956. He resigned after just over a year into his chief ministership after his delegation to London regarding negotiations for self-governance was rejected by the British.
Marshall was born in colonial Singapore to Jewish parents and studied at Saint Andrew's Secondary School and Raffles Institution. He held down different jobs from 1926 to 1934, eventually saving up enough money to study law at the University of London. He returned to Singapore in 1937 to begin his law practice. In 1938, Marshall began volunteering with the Singapore Volunteer Corps.
