Alan Turing and William Shockley

Whatever success I have in my life is due to two men, both scarred in life and death. We are now celebrating the 100th anniversary of the birth of Alan Turing who invented computational devices and who led the code-breaking work at Bletchley Park during the Second World War that brought an end to Hitler. William B. Shockley is a Nobel winner for his work on the invention of the transistor at Bell Labs, who later earned well deserved scorn for his views on eugenics and his overt racism. My hearing loss has been largely corrected by the work of these two men.
