Robert Wallace McLachlan

Robert Wallace McLachlan (9 March 1845 – 10 May 1926), was a prolific early Canadian numismatist, who published many works focusing primarily on pre-Canadian Confederation coins, tokens and medals. He lived in Montreal, and was for many years the Treasurer and Curator of The Canadian Antiquarian and Numismatic Journal. Along with fellow early Canadian numismatists Alfred Sandham, and P. N. Breton and Joseph Leroux, his publications are considered to have laid the foundations for Canadian numismatic research.

In 1894, P. N. Breton stated that McLachlan's coin collection was the most extensive in Canada with over 8,000 pieces, ranging from ancient Greek issues to contemporary coins. McLachlan sold his collection in its entirety to The Canadian Antiquarian and Numismatic Society of Montreal in 1922, which at that time had grown to an estimated 20,000 pieces.
