range from naturalist walk events to scientific congresses and presentations. A Harvard Museum of Natural History event in April of 2023 will also include a mixologist-designed special cocktail to honor Wallace's legacy. Memorials Mount Wallace in California's Sierra Nevada mountain range was named in his honour in 1895. In 1928, a house at Richard Hale School (then called Hertford Grammar School, where he had been a pupil) was named after Wallace. The Alfred Russel Wallace building is a prominent feature of the Glyntaff campus at the University of South Wales, by Pontypridd, with several teaching spaces and laboratories for science courses. Lecture theatres at Swansea and Cardiff universities are named after him, as are impact craters on Mars and the Moon. In 1986, the Royal Entomological Society mounted a year-long expedition to the Dumoga-Bone National Park in North Sulawesi named Project Wallace. A group of Indonesian islands is known as the Wallacea biogeographical region in his honour, and Operation Wallacea, named after the region, awards "Alfred Russel Wallace Grants" to undergraduate ecology students. Several hundred species of plants and animals, both living and fossil, have been named after Wallace, such as the gecko Cyrtodactylus wallacei, and the freshwater stingray Potamotrygon wallacei. Writings Wallace was a prolific author. In 2002, a historian of science published a quantitative analysis of Wallace's publications. He found that Wallace had published 22 full-length books and at least 747 shorter pieces, 508 of which were scientific papers (191 of them published in Nature). He further broke down the 747 short pieces by their primary subjects: 29% were on biogeography and natural history, 27% were on evolutionary theory, 25% were social commentary, 12% were on anthropology, and 7% were on spiritualism and phrenology. An online bibliography of Wallace's writings has more than 750 entries. References Notes Citations Sources Vol. 1 . Vol. 2 Further reading There is an extensive literature on Wallace.
