none 1835 science 1835 The year 1835 in science and technology involved some significant events, listed below. Astronomy August 5 – First sighting of the return of Comet Halley by Father Dominique Dumouchel, director of the Collegio Romano at the Vatican. It is next seen on August 21 by Friedrich Georg Wilhelm Struve at the Dorpat Observatory. John Herschel had been expected to find the comet first, as he is at the time in South Africa with his 20 ft focal length reflector – at this time the world's largest telescope. He finally observes it in October and watches until it reaches perihelion November 16. It reappears in January 1836, and Herschel will be the last person to observe it in May. August 25 – The first of six articles on discoveries of living creatures on the Moon supposedly made by Herschel and a fictitious companion named Dr. Andrew Grant is published in the New York Sun. This incident is now known as the Great Moon Hoax. Berlin Observatory opened. Caroline Herschel and Mary Somerville become the first women members of the Royal Astronomical Society. Biology January – J. C. Loudon begins publication of Arboretum et Fruticetum Britannicum.
