Delightful chap, who used to own a tool emporium in Sheffield.
Much of the collection is at Kelham Island Museum, and there’s 80+ videos here, featuring both archive footage and recordings of more recent lectures

The trust bearing his name has a huge collection of Sheffield tooling, some visible at the museum, and I believe other stuff available by appointment

Included in the trust’s links, also see Name on a Knife Blade

Some lectures coming up for anyone in travelling distance; it’s an easy walk from either bus or train stations, but if driving in a van, beware the clean air zone charges.
