William "Jock" Alves (c. 1909 – 10 February 1979) was a Scottish-born Rhodesian physician and politician who served as mayor of Salisbury (now Harare) from 1972 to 1974.
An epidemiologist by profession, he directed a bilharzia research laboratory in Salisbury and later worked with the World Health Organization on parasitic disease projects.
[2] He pursued his doctorate at the London School of Hygiene & Tropical Medicine, but had to return to Southern Rhodesia in 1947 before completing his degree.
[7] He was considered an international authority on bilharzia, and during his tenure at the laboratory developed a treatment for the disease that was successfully tested on 25 patients.
[15] In June 1978, Alves made a speech before the senate in which he urged the Rhodesian government to include the African nationalist leader Joshua Nkomo, and possibly Robert Mugabe, in any potential settlement negotiations.
