Edward Jenner, pioneer of vaccination, dead at 63 Also mourned: Angerstein, tycoon and art collector, and mathematician Hutton

Britain’s financial, arts, and academic communities have lost two more major international figures, with the deaths in January of businessman and philanthropist John Julius Angerstein, 87, and mathematician Charles Hutton, who was 85.

Reputedly born to the Russian empress Anna and a British merchant in St Petersburg, John Julius Angerstein spent more than half a century in the insurance business as a broker and underwriter, becoming a key figure at Lloyd’s of London.

One of the wealthiest men in Britain, his fortune enabled him to become an art conoisseur and philanthropist.

Mr Angerstein chaired the Jennerian Society for the Extermination of the Small Pox, secured grants from Lloyd’s for the construction of lifeboats and stations, donated о £61,000 to a school for naval orphans, and supported the Committee for the Relief of the Black Poor.

As an art collector Mr Angerstein amassed works by Claude, Rembrandt, Titian, Rubens, Wilkie and Hogarth. There is likely to be considerable jockeying for ownership of the collection after his death.

The mathematician Charles Hutton, who has also died, has been hailed by Sir Humphrey Davy as “one of the most able mathematicians of his country and his age”.

Born in Newcastle to a superintendant of mines, Charles Hutton worked briefly in a colliery but went to school instead after being injured in a street fight. He became a successful teacher and started his own school, applying maths to book-keeping, navigation and surveying.

For 30 years Mr Hutton was professor of mathematics at the Royal Military Academy He produced textbooks and calculated the mass and density of the earth.
