Mary Maydwell Martin (1915-1973) was an Australian bookseller.^[1] In 1945 she founded the Mary Martin Book Shop on Grenfell Street.^[2] In 1947 she asked Max Harris to become a partner in the shop, which by then had moved to Alma Chambers, 13 Commercial Place.^[3] Harris agreed; he also made a news-sheet which he called Mary's Own Paper, although it contained his own opinions.^[4]The shop expanded, and by 1955 it was located at 75 Rundle Street; by 1957 it was in a large part of the first floor of the Da Costa Building, Gawler Place.^[5] In 1962 Mary decided to move to India for good, having previously visited there in 1952, 1957, and 1961.^[6] Harris became the sole manager of the bookshop, and Mary sold her interests in the firm to him and Yvonne Harris.^[7]

The Mary Martin chain was sold to Macmillans in the late 1970s.^[8]

Mary was also a foundation member of the South Australian branch of the Contemporary Art Society of Australia, and in 1939 won the Tormore prize for English Literature.^[9]
