An entrepreneur who helped found Britain's first online bank. A philanthropist who fled Idi Amin's Ugana and is now on a mission to track down the undiscovered Albert Einsteins of Africa. He embarked on a search to find a long-lost sister in Uganda after thirty years; he once rocked an 'impressive' Afro; his backers number a former head of MI6, and during his honeymoon in Mexico he sneaked away from his wife to attend a maths conference. Oh, and he's hell-bent on making it into space. You've possibly never heard him, but he's just been named the most influential black person in the UK. Becky Milligan profiles Tom Ilube.
