Photographs of John Dalton

Abstract

I SHALL be glad if any readers of NATURE can assist me in tracing the present whereabouts (if still in existence) of three original photographs of Dr. John Dalton. These were taken in Manchester, at one sitting, somewhere about the year 1842, by the Daguerre process, then recently introduced into Great Britain, and so far as I know were the only photographs of the great chemist ever made. Their production has been wrongly attributed to John B. Dancer, the fact being that it was through Dancer's good offices that Dalton was induced to sit at the local Daguerre studio.
