Charles de Worms

Most of de Worms working life was spent as a chemist in the Institute of the Royal Cancer Hospital and Porton Down Experimental Station, producing numerous papers on cancer. He became interested in ornithology but lepidoptera was his main interest and he published a large number of papers and notes mainly in the Entomologist's Gazette and The Entomologist's Record and Journal of Variation. In 1962 he published The Macrolepidoptera of Wiltshire.

Baron Charles George Maurice de Worms (1903–1979) was an English chemist and lepidopterist.

Charles de Worms was born in Egham, Surrey, in 1903. He was the son of Baron Anthony Denis Maurice George de Worms (1869–1938) and Louisa Matilda Goldscmidt. His paternal great-grandfather, Solomon Benedict de Worms (1801–1882), owned large plantations in Ceylon and was made a Hereditary Baron of the Austrian Empire by Franz Joseph I of Austria (1830–1916), and his paternal grandmother was Henrietta Samuel.

His paternal great-great-grandmother was Schönche Jeannette Rothschild (1771–1859), thus his paternal great-great-great-grandfather was Mayer Amschel Rothschild (1744–1812), the founder of the Rothschild banking dynasty. As a result, his paternal great-great-great-granduncles were Amschel Mayer Rothschild (1773–1855), Salomon Mayer von Rothschild (1774–1855), Nathan Mayer Rothschild (1777–1836), Carl Mayer von Rothschild (1788–1855), and James Mayer de Rothschild (1792–1868). His great-great-uncles, who owned plantations in Ceylon with his great-grandfather, were Maurice Benedict de Worms (1805–1867) and Gabriel Benedict de Worms (1802–1881). His paternal great-uncle was Henry de Worms, 1st Baron Pirbright (1840–1903).
