Bertie Thomas Percival Barker

Bertie Thomas Percival Barker CBE (9 August 1877 – 19 December 1961) was an English horticulturalist, plant pathologist, mycologist, and botanist.

[3] From 1899 to 1904 he did mycological and botanical research under the supervision of Harry Marshall Ward[2] and held the post of demonstrator in the botany department of the University of Cambridge.

In 1905 Lloyd resigned and Barker became the institute's director and sought collaborators from the University of Bristol, about 6.5 km (4 miles) distant.

Barker and Joseph Hubert Priestley developed the institute and enhanced its prestige, helping cider production for large-scale factory operations and improved quality control.

[5] From 1912 until his retirement in 1943, Barker was the director of the Long Ashton Research Institute and also held an appointment as Professor of Agricultural Biology at the University of Bristol.
