T. IORWERTH JONES'S LIST OF
NOTABLE WELSH SCIENTISTS OF 1934

Bryn Jones

Introduction

T. Iorwerth Jones of the National Physical Laboratory published an academic article The Contributions of Welshmen to Science in the Transactions of the Honourable Society of Cymmrodorion in 1934 (1932-1933 volume, pages 40-232). This became a useful reference source for the study of the history of science in Wales.

Iorwerth Jones's index to Welsh scientists and its two appendixes are reproduced here. For further details, readers should refer to the original article.

His full article runs to nearly 200 pages. It gives short biographies and lists of academic publications by the people numbered from 1 to 93 in the main list. Jones also gave two appendixes to the index. One appendix listed Welsh Fellows of the Royal Society elected for political reasons. These were usually establishment or political figures who had an interest in science but who did not make significant contributions to science (however, there are some serious scientists among these: for example, John Dillwyn Llewelyn (1810-1882) of Penlle'rgaer was a pioneer of photography). The other appendix lists predominantly English-born scientists who lived in Wales at some time: notable figures include Alfred Russel Wallace (1823-1913), the co-discover of the evolution of species through natural selection, and Sir George Everest, who led the mapping of the Indian subcontinent and after whom a mountain was named.

It is possible to debate Jones's selection of people for inclusion. The article listed only men: no women were included. Some people listed had only very loose associations with Wales. For example, the scientific instrument maker Thomas Jones (1775-1852) and the astronomers Thomas Lewis (1856-1927) and Edward Roberts (1845-1933) were all born in London and had at most only a connection to Wales through descent. Iorwerth Jones's list is presented here without any changes.
