The presenter of many popular children's educational programs, he joined the cast of Strictly Come Dancing in 2012.
From the late 1970s to the mid-1980s, his programs explained scientific concepts to children in an easily-grasped form, making science cool.
On Strictly Come Dancing, he was matched up with Aliona Vilani, but the two were the first dancing couple to get eliminated.
In 1976, he married his second wife Diane. He had three children. His daughter Zoe Ball became a presenter for the It Takes Two programme, and a former contestant on Strictly Come Dancing.
Olympian Louis Smith and his professional partner were the winners of Strictly Come Dancing in the 10th series, in which Ball competed.
