Auguste-Arthur de la Rive

De la Rive was only 13 when Davy and Faraday came to stay as his father Charles Gaspard de la Rive’s guests; a deep and lifelong friendship with Faraday ensued. Ampère also came to stay with his father, and again became a good friend and influential colleague, who helped de la Rive confirm his specialised vocation as an electrical physicist; aged 21, de la Rive invited the older Ampère to visit and join in on one of his experiments. Henry also visited, while Le Verrier invited de la Rive to demonstrate his apparatus reproducing the behaviour of terrestrial aurorae. Airy, Babbage and Ørsted all corresponded with him.
