Basil Schonland

Basil Ferdinand Jamieson Schonland, South African physicist (Grahamstown, Cape Colony 01 February 1896 – Winchester, Hampshire 24 November 1972) ACHIEVEMENTS Considered as world’s greatest authority on lightning Studied electric fields under thunderclouds Elucidated the complex nature of the lightning flash and the time-sequence of its component strokes Unravelled the complex sequence of events in the flash and correlated with the measurements of electric field changes at ground level First showed that a flash consist of several strokes and measured the time interval between them With D.J. Malan & H. Collens established a pattern of flash sequences of strokes now universally accepted (1935) First linked radio atmospherics with lightning (1935) Explained why spires and towers are more vulnerable to be struck by lightning DEVELOPED A new electroscope.
