Edward Wilfrid Baxby (Ted) Proud (April 1930 – 6 February 2017) was a British postal historian, philatelic writer, and philatelic dealer who, in 2008, was invited to sign the Roll of Distinguished Philatelists.
Proud won a gold medal for his display of Aden at Espana 2004 and exhibited "India used in Malaya" in the Court of Honour at Singapore.
In 2005, Proud won the Webb Cup from the Hong Kong Study Circle for his work The Postal History of Hong Kong 1841-1997.
In 2008, he was invited to sign the Roll of Distinguished Philatelists.
Proud founded Proud-Bailey Company Limited in 1961 through which he has published handbooks covering the postal history of over eighty different British colonies and which illustrate more than 50,000 postal markings. He is a past president of the International Federation of Stamp Dealers Associations and was the founder of Postal History International magazine in 1972. He was on the council of the Philatelic Traders Society.
Proud-Bailey became a major postal history dealer. In March 1987, Proud sold the firm to Stanley Gibbons, as a result of which he became joint deputy-chairman of Stanley Gibbons. The consideration for the sale was £1.6m, satisfied by the issue of 13 million new ordinary 10p shares in Stanley Gibbons at 12.25p each.
