Named in memory of William Thynne Lynn (1835–1911), assistant at Greenwich Observatory from 1854 to 1880 and author of several popular books. He is best known, however, for the numerous short notes on astronomical matters he wrote in The Observatory for many years. Among those notes is an enigmatic one in 1902 in which he hinted that the Perseid comet P/Swift-Tuttle {see also planets  (5035),  (5036)} might be identical with Kegler’s {see planet  (5005)} comet of 1737.
