Early life

Claud Alley Worth was born in Holbeach, Lincolnshire in 1869, the son of Thomas Mordaunt Worth, scion of an ancient Lincolnshire family,[1] and Frances Charlotte (née Alley).[6] He was educated at Bedford Modern School between 1884 and 1887[7] and St Bartholomew's Hospital.[1] He qualified as MRCS and LRCP in 1893 and was elected FRCS in 1898.[1][8]

Career

Worth began the study of ophthalmology under Henry Power and Bowater Vernon at St Bartholomew's Hospital and in 1906 joined the staff of Moorfields.[1] He was, for many years, ophthalmic surgeon to the West Ham Hospital in the East End of London.[1]

Worth gained fame in two diverse areas of specialisation: the management of childhood squint[9] and amblyopia, and the sailing and navigation of small yachts.[1][10][11][12] His inventiveness endures, as demonstrated by Worth's 4 dot test and later versions of his original amblyoscope.[1][2][8][13]

Worth's name and books were also familiar to sailors of small yachts.[1][10] He was 'deeply knowledgeable about currents, harbours and all aspects of seamanship'.[1][10] He was president of the Little Ship Club, Vice-Commodore of the Royal Cruising Club and a Master mariner.[1][10]

Personal life

Worth married Janet Duncan Ritchie in Sutton Bridge, Lincolnshire in 1906.[14] He died in Falmouth, Cornwall, on 24 June 1936 and was survived by his wife and a son.[1]
