Peter Findon Bethune Alsop was an Australian engineer and historian from Geelong, Victoria. He was responsible for researching and preserving many important road bridges and historic buildings in Geelong and the Victorian Western District. Alsop was an engineer with the Country Roads Board for the Geelong District, and while in this position argued successfully in a number of cases, that new improved road alignments were needed where bridges were to be replaced, and that this would incidentally save an historic bridge at the same time. Alsop was on the committee of Engineering Heritage Victoria, and the National Trust of Australia. Alsop was president of the Geelong Historical Society from 1984–2007 His large corpus of publications has been indexed and referenced by the State Library of Victoria.
