Professor Gwynne- Vaughan. By Professor F. O. Bower, F.R.S. 
(MS. received December 13, 1916.) 
By the death of Professor David Thomas Gwynne- Vaughan, which took 
place at Reading on September 4, 1915, the Royal Society of Edinburgh 
has lost a Fellow of high scientific standing, and one whose title to fame 
was in an essential part based upon work published by the Society itself. 
He had a very high regard for the Society. On the other hand, the 
Society had signalised its appreciation of the merits of his work, not only 
by accepting it for publication in a sumptuous form, but also by the award 
to him in 1910 of the MakDougall-Brisbane Medal. He was elected a 
Fellow in the same year. He was only forty-four years of age when he 
died, so that in the normal course much more scientific work of high 
quality might reasonably have been expected from him. 
He was born on March 12, 1871, at Royston House, Llandovery, 
being the elder son of Henry Thomas Gwynne- Vaughan of Cynghordy, 
later of Erwood Hall, Breconshire. His mother was Elizabeth, second 
daughter of David Thomas, of Royston House, Llandovery. She died in 
1874, and Professor Gwynne- Vaughan was her only child. He went to 
school at Monmouth in 1882, and proceeded with an exhibition from school 
to Christ’s College, Cambridge, where in 1891 he was elected to a scholar- 
ship in science. In 1893 he took a First Class in the Natural Sciences 
Tripos, and left Cambridge to take up a Mastership. This, however, 
he soon relinquished in order to enter on research. With this object he 
went to Kew, and was admitted to the Jodrell Laboratory within the 
Royal Gardens. 
This move was the determining point of his career. For the laboratory 
was then under the direction of Dr D. H. Scott, who soon recognised the 
qualities which had passed unnoticed among the crowd of undergraduates 
at Cambridge. Wittingly or unwittingly, Gwynne- Vaughan had come 
under the influence of the very investigator by whom his patient and 
acute powers of observation could best be directed into that channel 
of anatomical inquiry which he subsequently did so much to advance. 
Stelar problems were in their infancy in 1895. Van Tieghem had broken
