She was awarded an honorary degree in 1992.
Deaf since the age of eight, Dame Kathleen was a former chairman of Manchester education committee and Lord Mayor of the city, where she was born and died. She was an adviser on education to the Government in the 1980s.
Dame Kathleen was the driving force behind the creation of the Royal Northern College of Music. She was made a dame for services to education and was given the freedom of Manchester.
Her husband Robert died in 1986 and both their son and daughter also died.
