J. J. Thomson

Routh and his pupils for the Mathematical Tripos of January 1880. Thomson is
third from the right in the back row; Larmor is second from the left in the
row. At the time there was no supervision for undergraduates. Instead, those
aspiring to a high place in the Mathematical Tripos went to a `coach', who
provided intensive teaching. Routh was the most famous coach, and the period
1855-1888 he taught 27 Senior Wranglers. Each pupil paid £36 p.a., which
was a large sum for a poor student like Thomson, but he though `the teaching
was worth the expense'.
(From Thomson's autobiography)

The research students of the Cavendish Laboratory in June 1897. Thomson is fourth from the left in the front row, Rutherford is at the right-hand end of the row, and C.T.R. Wilson, the inventor of the cloud chamber, is second from the left in the back row.
