Description
Dr. W.A.R. Dillon Weston spent all of his professional life in Cambridge. After obtaining his degree in Natural Sciences at St. Catharine’s College, Dr. Dillon Weston gained employment as a mycologist (an expert in the study of fungi) at the Ministry of Agriculture and Fisheries. Ministry Pathologists at that time were stationed at universities, where teaching and supervision of students were included as part of their duties.
During the 1930’s, Dillon Weston produced nearly 1,000 watercolour paintings of plants suffering from a wide variety of afflictions: mostly various fungal infections, but also pest attacks, nutrient deficiencies, and bad farming practices. These drawings were produced in connection with his position at the Ministry, which he described as forming a “link between the farm and the research station.” Farmers would send samples of afflicted crops to the Ministry, and Dillon Weston would diagnose the problem and offer solutions. This work was an example of the emerging school of “New” or “Economic” Botany, in which economically important plant diseases were studied with an eye to increasing crop yields.
Typed notes accompanying the paintings suggest that many of them were depictions of samples received by Dillon Weston at the Ministry, though it is unclear why he made them. Like his glass fungi models, also held by the Whipple (Wh.5826), the paintings may have been a hobby undertaken during bouts of insomnia. Some of the paintings are demonstrative or didactic in nature, and Dillon Weston may have used them in his lectures at the university, which he endeavoured to make “as interesting as possible,” according to a 1952 profile in Varsity, the Cambridge student newspaper.
The paintings demonstrate a careful attention to detail and a desire for accurate representation, which sometimes led Dillon Weston to push up against the limits of flat, two-dimensional representation. For example, he used painted cotton stuffing underneath layers of paper to imitate spores bulging up underneath a scab on an apple tree (Wh.6662.28, Wh.6662.29), and splashes of blue watercolour paint to demonstrate how far fungal spores can be spread by raindrops (6662.10).
