Yes. The 'astral' discovery made by William Herschel in 1781, he proposed it be named Georgium Sidus in honour of George III - a proposal accepted in England but not elsewhere, possibly because he thought it was a comet rather than a planet. The name suggested (and approved elsewhere) by Johann Bode in 1782 - Uranus - who identified it as a planet, was eventually accepted in England 70 years later. Over to you.
Less a valet though, he was oft treated as such, more a personal assistant... went on to even greater things than his mentor...
To help along with the "tenuous links"... The answer to my previous question was Humphry Davy. The person who is being referred to was often treated as a valet but eventually outshone his employer / mentor and is pretty much a household name. Benzin isn't quite a literal translation but the pronunciation gives the clue. The pilot episode of Star Trek is called "The Cage"... (Captain Pike at the helm of the Enterprise before James T. Kirk - a prequel of adventures has been made by one of the streaming sites, Amazon I think). Should give it away now.
He started out as a chemist but he is famed for his work with electro magnetism and showed that electricity was a force. He built a framework... stepped inside, electrified it, and stepped out unharmed after the current was turned off.... The principle is named after him...
Yes. Michael Faraday. He was Humphrey Davy's assistant but treated more like a valet than a junior partner. He discovered Benzene which gives petrol its distinctive smell. An aromatic hydrocarbon. Faraday's Cage, to answer the clueses. Over to you.
In 1959 the first one was appointed in France. To date only two have been female. The post has no time limit on it. The President cannot sack them. Who are the two women and what post is it?
A clue. The first one was a very popular figure for a long time in my département, but not nationally, resigning after less than a year.
