Dame Kathleen Ollerenshaw was born Kathleen Timpson in 1912. Deaf from an early age, she went on to have a brilliant career and is best known for her contribution to pandiagonal magic squares. She was also heavily involved in the establishment of the Royal Northern College of Music and was an advisor to Mrs Thatcher's government on education. She died aged 101.

Nominator Sir John Timpson is chairman of the high street shoe repair shop that bears his family name and knew Dame Kathleen extremely well. Her spirit and determination shine through. Also in studio is Dr Ems Lord, research fellow at Clare Hall and director of NRICH.
