Mathematician. Born in Keighley in 1823, Parkinson entered St John's College as a sizar in 1841. He graduated as Senior Wrangler in 1845, famously beating William Thomson into second place, and was elected to a Fellowship at St John's in the same year. Parkinson was the author of two mathematical textbooks, 'Elementary Treatise on Mechanics' (1855) and 'A Treatise on Optics' (1859), both of which went through several editions and remained in use for 25 years. He served his College as lecturer in mathematics, tutor (1864-82) and President (1865-89). Parkinson also served on the committee of the University Senate (1866-1878), and was made a Fellow of the Royal Society in 1870. He was ordained in 1851, received his BD in 1855 and his DD in 1869.
19 notebooks containing mathematical notes and examples, possibly used by Parkinson for coaching students. Topics covered include: Newton, dynamics, hydrostatics, tides, statics, instruments, undulatory theory, mechanics, and planetary theory.
