designation
(2718) Handley was named after the United Kingdom entertainer Tommy Handley (1894-1949) , who was known during World War II . He began his career in variety and concerts , but found in 1926 that his very fast style of spoken humor suited the new medium of radio . His greatest success was the radio program " It's That Man Again " (ITMA), which was first broadcast in 1939. The naming was suggested by the American astronomers Brian Marsden , Gareth V. Williams and Robert Williams .
