From Facebook this morning:-
"It is with tremendous sadness that Henry Willis & Sons Ltd. has reported the death of Henry Willis 4 b. 19th Jan 1927 - d. 23rd June 2018
Mr. Willis was the last member of the Willis dynasty to be materially involved in the family firm from which he stood down as Managing Director on his birthday in 1997, later appointing David Wyld to the position: he continued as the Majority Shareholder until the 28th November 1998.
An obituary has been written by Bruce Buchanan and will appear in The Times tomorrow."
