Harry Hugh Wormald

Harry Wormald was christened on 16 November 1879 in Luddenden.{{cite web|title=Harry Wormald, England Births and Christenings, 1538-1975|url=https://www.familysearch.org/ark:/61903/1:1:NF3Y-49Q |website=FamilySearch }} After being trained as a school teacher, he taught in Yorkshire schools from 1900 to 1908. In 1908, with the aid of a scholarship from the London School Board, he matriculated at the Royal College of Science of Imperial College London. He graduated there in 1911 with a B.Sc.{{cite book|url=https://books.google.com/books?id=thmPzIltAV8C&pg=PA757 |page=757 |title=Dictionary of British and Irish Botanists and Horticulturists Including plant collectors, flower painters and garden designers | isbn=9780850668438 | last1=Desmond | first1=Ray | date=25 February 1994 | publisher=CRC Press }} and was awarded an A.R.C.S.{{cite journal|author=Harris, Ralph Vivian|title=Dr. H. Wormald|date=April 7, 1956|journal=Nature|volume=177|issue=4510|page=649|doi=10.1038/177649a0 |bibcode=1956Natur.177..649H |s2cid=4191987 |url=https://www.nature.com/articles/177649a0.pdf}} With another scholarship, he started research at Imperial College London and was awarded in 1912 a Diploma of Imperial College and in 1919 the D.Sc. From 1911 to 1923 he worked as an assistant to Ernest Stanley Salmon at Wye College. There Wormald did important research on the fungus Monilinia fructicola, which causes brown rot in cherries, plums, peaches, and apricots.

In 1923 Wormald was appointed the head of the plant pathology section of the East Malling Research Station (EMR). There, under the directorship of Ronald George Hatton, he worked until 1945. In 1936 Wormald was appointed EMR's assistant director and held that appointment until his retirement in 1945. In 1936 he made the important observation that, for the bacterial canker disease Pseudomonas syringae of cherry trees, branch cankers often develop from previously infected fruiting spurs.{{cite journal|author=Wormald, H.|title=Bacterial canker in plum and cherry trees|journal=Ann. Rep. East Mall. Res. Sta. 1936|year=1937|pages=297–301}}{{cite journal|url=https://www.nature.com/articles/168560b0 |doi=10.1038/168560b0 |title=The Leaf Scar as an Avenue of Infection for the Cherry Bacterial Canker Organism, Pseudomonas mors-prunorum Wormald |date=1951 |last1=Crosse |first1=J.

Gummosis and sour sap are synonyms for bacterial canker of cherry trees.) For ten years, beginning in 1935, he edited EMR's Annual Report. For the British Mycological Society, he served as the president for one year from 1940 to 1941 and was the joint editor of the Transactions of the British Mycological Society from 1931 to 1945. For the Association of Applied Biologists (AAB), he served on the AAB's Council from 1937 to 1939 and as the vice-president from 1938 to 1939. In 1945 Wormald became a staff member of the Commonwealth Bureau of Horticulture and Plantation Crops, stationed at East Malling. There he worked for seven years as an abstractor of horticultural literature for many different languages — he could expertly translate seven foreign languages into English. During the last three years of his life he suffered from severe disease, but with the help of his wife, he was able to prepare new editions of his two principal works, The Brown Rot Diseases of Fruit Trees and The Diseases of Fruits and Hops.
