Lady Soames had maintained a connection with the school and was a patron of the Berkhamsted Foundation.
The school’s principal Mark Steed, said: “We are deeply grateful to the contribution by Lady Soames in supporting The Berkhamsted Foundation in its efforts to create sustainable and long-term funding to invest and build for present and future generations.
“She led a fascinating life and met many famous people. I asked Lady Soames who she had found the most interesting and she replied, ‘Lawrence of Arabia was charming; he used to get up early and help with the feeding of my animals’.”
Lady Soames opened Churchill Hall, named in her mother’s honour, atBerkhamsted Preparatory School in October 1999.
