Colin Gregg was a well-known figure in the North East.
He helped raise millions of pounds for various children's charities and even hosted royalty when promoting the Yellow Brick Road fund for children.
The son of Greggs bakery founder John Gregg, he took up teaching at the prestigious Durham School, his former school, in 1964.
Three years later he joined his brother to build up the family business.
He later became a social worker for Newcastle City Council, before returning to teaching and eventually becoming a headteacher at the former Kings School in Tynemouth in 1978.
He had power, wealth and was in a position of trust and authority - a position he used to sexually exploit children.
On Friday Gregg was found guilty of nine counts of indecent assault against four boys aged between 11 and 14 over three decades.
Steven Tait from the children's charity NSPCC said Gregg's actions were "appalling."
He said: "It's appalling what’s happened and what Colin Gregg has done. "It's the right verdict. Somebody like Colin Gregg is trusted in his community, somebody with influence and power and often people don’t believe that somebody like that would abuse children."
A national spokesman for the charity praised the bravery of the young victims who came forward.
