Einstein thought it would be relatively easy to attend;
Volta was electrified and Archimedes, buoyant at the thought;
Ampère was worried he wasn't up to current research;
Ohm resisted the idea at first;
Boyle said he was under too much pressure;
Edison thought it would an illuminating experience;
Watt reckoned it would be a good way to let off steam;
Stephenson thought the whole idea was loco;
Wilbur Wright accepted- provided he and his brother, Orville, could get a flight;
Dr. Jekyll declined, on the grounds that he hadn't been feeling himself lately;
Morse's reply? "I'll be there on the dot. Can't stop now- must dash."
