  His Edinburgh and Cambridge mentors were to shape Darwin’s philosophical attitudes and scientific career decisively.  It was Henslow who was the final link to Darwin in a chain connected to Captain Robert Fitzroy of H. M. S. Beagle. Fitzroy sought a gentleman companion who could also collect information on geology and natural history during a proposed circumnavigation of the globe. Henslow’s note to Darwin, asking if he would be interested in being recommended for this post, arrived at the Darwin home, ‘the Mount’, while Charles Darwin was on a geological survey of Northern Wales with Adam Sedgwick. After resistance from his father had been overcome, Darwin was offered the post and accepted it.
