Gilchrist Walker was one of the successful Anglo-Levantine shipping brokerage companies based in Galata whose hayday was in the late 19th century, but it did maintain its business till the middle of the 20th century. Charles Wilkinson who joined the company in 1952 became the director in 1957 of this shipping agency, (which originally had had a large J.W. Whittall & Co. interest) changed its name and through hard work turned this business to a very successful venture.
