Willoughby Wallace Hooper (1837 in Kennington, south London – 21 April 1912 in Kilmington near Axminster, England) was an English military officer and photographer, serving for near to forty years in the colonial army in southern India and British-Burma during the second half of the 19th century.

Having been published in Britain under the title Secundarabad, and with captions such as "Deserving Objects of Gratuitous Relief",[8] they were caricatured by the satirical magazine Punch, criticizing Hooper for not having given any help to the people he was about to depict.

In 2021, articles in the journal History of Photography and the Indian magazine Scroll.in, cited these pictorial documents of atrocities as historical examples for questions about the photographer's ethical responsibility and their effects on the general public.

[9][10] Some of his pictures showing the execution of Burmese prisoners became notable for the investigation following allegations that Hooper had them treated cruelly and inhumanely by delaying the firing squad for the time necessary to take the photographs.

[11] Shortly afterwards, the affair also raised issues over the ethical role of the photographer in documenting human suffering and the moral justification of carrying out executions against "a conquered people".
