‘Count Rumford called but seldom’

share this

Who would be the equivalent today of the American physicist Sir Benjamin Thomson, Count Rumford, FRS (1753-1814)?

A quick review of the current fellows of the Royal Society, filtered by the scientific area of ’physics’ and a free text search for a ‘Sir’ brings up the engineer Lord Broers – an expert in nanotechnology and former Chairman of the House of Lords Science and Technology Committee.

He sounds rather important, and if he was calling round to see my father (rather than summoning my father to a meeting at his own convenience), I might think the fact was worth recording in some detail.

Frustratingly, William Nicholson’s son and biographer leaves us with nothing more than that short phrase ‘Count Rumford called but seldom’ in his memoir of his father The Life of William Nicholson (1753-1815).

There is no hint to the object of their discussions – although they might have related to Nicholson’s work on the Committee of Chemistry at the Royal Institution.

From the perspective of young William, Count Rumford was just one of many estimable visitors who worked with his father in various societies, attended Nicholson’s scientific lectures or weekly conversazione, or consulted him on patents or matters of civil engineering.

With the names of his father’s associates including the likes of Josiah Wedgwood, Matthew Boulton, Richard Kirwan, Sir Joseph Banks, Humphry Davy, Frederick Accum, Richard Trevithick, Jabez Hornblower, Jean-Hyacinth Magellan and Anthony Carlisle, one can see how young William might have become blasé about one more 'important' visitor.
