John Gwyn Jeffreys -- His life and his legacy
Abstract
John Gwyn Jeffreys was one of the top molluscan taxonomists and collectors in the 1800s and was one of the pioneers in deep-sea dredging. The results of his work can be seen in his papers, namely those of the cruises of the Lightning, Porcupine, Valorous and Knight Errant, which are still relevant today. He was taught how to collect shells by one of his teachers and at the age of 19 was encouraged by Dillwyn, renowned conchologist, to write his first scientific paper. At the age of 20 he became an elected fellow of the Linnaean Society. Jeffreys went on to write over 200 papers, describe 41 new genera and 585 new species.

On this occasion I propose to adopt the same course that was taken in presenting to the Royal Society the Preliminary Report of the scientific exploration of the deep sea in H. M. Surveying-vessel ‘Porcupine’ in the years 1869 and 1870, in both of which expeditions I took a part. Narrative. 1. The Government having, at the instance of the Society and other scientific bodies, determined to equip and send out last year two ships (the ‘Alert’ and ‘Discovery’) on a North-Polar Expedition, and with these vessels the ‘Valorous’ frigate as a store-ship to accompany them as far as Disco in Davis Strait, it was considered desirable to make the last-named vessel available for sounding and dredging on her return voyage. Accordingly the following correspondence with the Admiralty took place, and will serve to explain the circumstances under which the scientific results now about to be noticed were obtained.
The following Extracts from the Minutes of the Council of the Royal Society set forth the origin of the 'Porcupine’ Expedition, and the objects which it was designed to carry out. January 21, 1869. The Preliminary Report of the Dredging Operations conducted by Drs. Carpenter and Wyville Thomson (in the ‘Lightning’) having been considered, it was Resolved,—That, looking to the valuable results obtained from these Marine Researches, restricted in scope as they have been in a first trial, the President and Council consider it most desirable, with a view to the advancement of Zoology and other branches of science, that the exploration should be renewed in the course of the ensuing summer, and carried over a wider area; and that the aid of Her Majesty's Government, so liberally afforded last year, be again requested in furtheranceof the undertaking.
