Sad news in the UK #histSTM community - my former University of Kent colleague and admired historian of 19thC energy physics and steam ocean navigation, Crosbie Smith, died at the weekend following a short illness. We owe him a great deal.

Just wasted half an hour in Google streetview trying to find transistor-shaped street sculptures outside the site of the original Shockley Semiconductor Laboratory at 391 San Antonio Road. They’ve vanished

Got lost. Now stuck in car park. It’s hot and sunny

Anyone know what happened to them?

The National Museums and Galleries of Wales (which does not have that money to hand) make a counteroffer

It’s a “highly significant heritage object, of great importance to the history of Wales, and subsequently to the coal industry during the period of nationalisation”

Perhaps for free as a gift?

The Coal Board Corporation offer it to the National Museums and Galleries of Wales

But, wringing their hands, they say they have “a statutory duty to dispose of assets on the best possible terms”

It’s pure silver. It’s worth £250,000

(This selling of silver is the METAPHOR for privatisation)

But what about the Mitchell-Hedges silver trophy for coal mine first aid?

In 1994, Mitchell-Hedges’ daughter (not the skull one, surely) is inquiring about it…

Whitehall, bless them, says ”it is essential that we do the proper thing and do not allow the trophy to become ‘lost’ on privatisation”

He is perhaps most well-known for the “Mitchell-Hedges crystal skull”, that he claims his adopted daughter found in (what is now now) Belize in 1924

(he almost certainly purchased it from a dealer in the 1940s. It was almost certainly recently made)

This is the unexpected Indiana Jones reference

Frederick Albert Mitchell-Hedges was an “adventurer”, a traveler and teller of tall tales. At one stage he is captured by Pancho Villa in Mexico. He has a radio show.

It had been presented by Mr Mitchell-Hedges to his friend, coal chairman Lord Hyndley in the 1940s

It was awarded for a while to the miners who mined the most coal, as a kind of spur to productivity

Then it became a yearly prize in a First Aid competition, which continued right up to 1990s
