Hi all,
Tony Simcock has written an excellent obituary of Allan Chapman for the Journal of the Scientific Instrument Society. (Thanks to Roger Hutchins for pointing this out)
The following is a link to the appropriate page of the SIS web site, where Tony has arranged for the article to be freely accessible to non-members.
Bulletin 168 March 2026 – Scientific Instrument Society
In addition both the chairman of the Society & the Editor (Prof. Willem Hackman) pay nice tributes to Allan on page 1 of the Bulletin, with an additional picture of him, nicely supplementing Tony’s obituary, and this page is also (separately) freely accessible from the web page the above link takes you to.
I am currently working on Allan Chapman’s obituary for the BAA Journal.
