Alfred Russel Wallace hath a Rottweiler. Darwin obviously had a Beagle but the Beagle had a captain, Robert Fitzroy.
Fitzroy was 26 when he was given orders to take Beagle around the world and the fact that Darwin arrived in Falmouth in once piece with notebooks full of Good Things is in no small part due to Fitzroy's powers of command and seamanship. Some of the conditions he sailed through would make most modern sailors wet their oilskins from the inside.
2009 is Darwin's year, but as a sailor I don't want this great sailor forgotten in the welter of Darwiniana. Sailors have him to thank for pioneering weather forecasting using barometric pressure and he became the founding head of what has become the Meteorological Office. I suspect he saved a lot of seafarer's lives.
A Fitzroy page was on the to-do list, but an email from science author John Gribben has prompted me to get on with it. It will be posted soon.
