Telephotography: An elementary Treatise on the Construction and Application of the telephotographic Lens … with twenty-six plates and sixty-six diagrams.
First edition of the authoritative treatise on telephotography by the inventor of the first practical telephotographic lens.
Thomas Rudolphus Dallmeyer (1859–1906) was the son of John Henry Dallmeyer (1830–1883), to whose memory the book is dedicated, a noted optician and lensmaker who made advances in the designs of both tele- and microscopic and photographic lenses. The younger Dallmeyer developed the first practical telephotographic lens, patented in 1891, for which he won the Royal Photographic Society Medal in 1896, and was elected President of the Society in 1900. Dallmeyer here outlines the scientific underpinnings of telephotographic lenses and compares their performance and structure with both astronomical telescopes and with the ordinary lenses of the era. He proposes that telephotography is not only invaluable for its ability to capture objects far away, but also for its use in magnifying objects in medical, geological, and naval contexts, inter alia.
Provenance: with the bookplate of Lionel Nathan de Rothschild (1882–1942), Partner at New Court Rothschild Bank, Conservative Member of Parliament, and an avid photographer who experimented with the autochrome from its first release in Britain in 1907.
