John Witherspoon Bald (born April 7, 1868, Parsonstown, Ireland - died 1961, Midland, Ontario, Canada) was a Canadian photographer who produced portraits, landscape and other commercial photographs.
Bald worked for both Midland newspapers, the Free Press and the Argus, and also developed an extensive post card business.
His photographic career began shortly after the introduction of gelatine dry plate photography.
This type of plate was commercially prepared and could be stored prior to exposure.
The Huronia Museum in Midland has an extensive collection of Bald’s photographs, postcards, and equipment.
