THANK you to the many former pupils and staff of Alexandra School, Hounslow, who replied to my request for information about teacher Peter Sheffield and his parents (Chronicle, June 25).

I had no idea 'Sheff' would be so well remembered. There are too many letters for me to reply to them all individually, but I am most grateful to everyone who took the trouble to write and share their recollections, and for suggesting further sources of information.
