John Louis Emil Dreyer – författare

By the time of his death, William Herschel (1738-1822) had built revolutionary telescopes, identified hundreds of binary stars, and published astronomical papers in over forty volumes of the Royal Society's Philosophical Transactions. This two-volume collection, which originally appeared in 1912, was the first to gather together his scattered publications. It draws also on a wealth of previously unpublished material, from personal letters to numerous papers presented to the Philosophical Society of Bath. Although Herschel is best known for his discovery of Uranus, this collection highlights the true range of his observations and interests. Focusing on his early work, Volume 1 includes notes on the discovery of Uranus, unpublished papers on electricity, and studies of the lunar mountains and the poles of Mars - both of which he believed to be inhabited. It also features a biographical account by the historian of astronomy J. L. E. Dreyer.

Although Herschel is best known for his discovery of Uranus, this collection highlights the true range of his observations and interests. Focusing on his later work, Volume 2 includes notes on some of the moons of Uranus, studies of solar heat and the atmosphere of Saturn, and some practical experiments investigating the capabilities of contemporary telescopes. It also features an appendix of work compiled by his son, John Herschel, and sister Caroline.

Founded as the Astronomical Society of London in 1820, this illustrious organisation received its royal charter in 1831. It has counted some of the world's greatest astronomers among its members, most notably its first president, Sir William Herschel, whose family archive forms part of its extensive library. Now based in Burlington House in Piccadilly, it continues to publish journals, award medals and prizes, and support education and outreach work. Following the society's centenary, this survey of its history appeared in 1923 and comprises contributions from leading astronomers of the early twentieth century. The extracts from primary sources include the diary entry of Sir John Herschel, son of William, recording the dinner at which the society's formation was discussed. The work also provides insights into how the society was able to take advantage of imperial expansion to collect observations and data from around the world, fuelling the Victorian pursuit of scientific knowledge.

Famous for his metal prosthetic nose, and for being associated with 'unlucky' days in Scandinavian folklore, Tycho Brahe (1546-1601) made the most accurate naked-eye astronomical measurements of his day. Cataloguing more than 1,000 new stars, his stellar and planetary observations helped lay the foundations of early modern astronomy. John Louis Emil Dreyer (1852-1926) was a fellow Dane, but he spent much of his working life in Ireland. When he was fourteen, he had read a book about Brahe and this inspired him to 'be an astronomer and nothing else'. First published in 1890, Dreyer's biography of his hero remained the definitive work for more than a century. He sets out to illuminate not simply the life of his subject, but also the lives and work of Brahe's contemporaries and the progress of science in the sixteenth century.
