Walter Henry Guillebaud, CBE (2 July 1890 – 1 November 1973) was a British civil servant and forester.
[4] By the late 1940s, Guillebaud had been "the leading figure in forest research since the early twenties".
[5] He served as president of the Institute of Foresters of Great Britain from 1945 to 1947[6] and published ten articles in its journal, Forestry.
B. Macdonald recalled him as "cadaverous in appearance [but] nevertheless gentle, retiring and timid by nature... [h]e was definitely a scholar by preference, and I doubt if there was very much that was really original either about his work or his thoughts".
[3] He was appointed a Commander of the Order of the British Empire (CBE) for his service in the 1951 New Year Honours.
