Darwin Day is a celebration to commemorate the birthday of Charles Darwin on 12 February 1809. The day is used to highlight Darwin's contributions to science and to promote science in general. Darwin Day is celebrated around the world. History The celebration of Darwin's work and tributes to his life have been organised sporadically since his death on 19 April 1882, at age 73. Events took place at Down House, in Downe on the southern outskirts of London where Darwin and members of his family lived from 1842 until the death of his wife, Emma Darwin, in 1896. In 1909, more than 400 scientists and dignitaries from 167 countries met in Cambridge to honour Darwin's contributions and to discuss vigorously the recent discoveries and related theories contesting for acceptance. This was a widely reported event of public interest. Also in 1909, on 12 February, the 100th birth anniversary of Darwin and the 50th anniversary of the publication of On The Origin of Species were celebrated by the New York Academy of Sciences at the American Museum of Natural History. A bronze bust of Darwin was unveiled. On 2 June 1909 the Royal Society of New Zealand held a "Darwin Celebration". "There was a very large attendance." On 24–28 November 1959, The University of Chicago held a major celebration of Darwin and the publication of On the Origin of Species, the largest event of the Darwin Centennial Celebration. Scientists and academics sometimes celebrated 12 February with "Phylum Feast" events—a meal with foods from as many different phyla as they could manage, at least as early as 1972, 1974, and 1989 in Canada. In the United States, Salem State College in Massachusetts has held a "Darwin Festival" annually since 1980, and in 2005, registered "Darwin Festival" as a service mark with the US Patent and Trademark Office. The Humanist Community of Palo Alto, California, was motivated by Dr. Robert Stephens in late 1993 to begin planning for an annual Darwin Day celebration. Its first public Darwin Day event was a lecture by Dr. Donald Johanson (discoverer of the early hominid "Lucy"), sponsored by the Stanford Humanists student group and the Humanist Community on 22 April 1995. The Humanist Community continues its annual celebration. Independently, in 1997, Professor Massimo Pigliucci initiated an annual Darwin Day event at the University of Tennessee. The event included public lectures and activities as well as a teachers'
