Alan Turing will be on England's £50 note

Computer scientist Alan Turing, key to decoding Nazi communications during World War II, is to be the face of the new £50 banknote. The BBC:

The work of Alan Turing, who was educated in Sherborne, Dorset, helped accelerate Allied efforts to read German Naval messages enciphered with the Enigma machine.

Less celebrated is the pivotal role he played in the development of early computers, first at the National Physical Laboratory and later at the University of Manchester.

In 2013, he was given a posthumous royal pardon for his 1952 conviction for gross indecency following which he was chemically castrated. He had been arrested after having an affair with a 19-year-old Manchester man.

Also, artist Turner on the Twenty:

The Jane Austen tenner entered circulation in 2017. Churchill's on the fiver. Queen Liz is, of course, on all of them.

There hasn't been a £100 in circulation from the Bank of England for decades (The Bank of Scotland has one, with founder Archibald Campbell on it). They should do a run and put Ira Aldridge or Mary Seacole on it.
