Christine Buisman

Christine Johanna Buisman (Dutch pronunciation: [krɪsˈtinə joːˈɦɑnaː ˈbœysmɑn]; 22 March 1900 – 27 March 1936) was a Dutch phytopathologist who dedicated her short career to the research of Dutch elm disease and the selection of resistant elm seedlings. In 1927, Buisman provided the final proof that Graphium ulmi (later named Ophiostoma ulmi) was the causal agent of the disease, concluding the controversy which had raged among Dutch and German scientists since 1922.

Buisman developed the inoculation method for screening large numbers of elm plants for resistance, and in 1932 discovered the generative form of the fungus, Ceratostomella ulmi. The first ever resistant elm clone released in the Netherlands was named for her in 1937, following her untimely death the previous year.
