Death of Wilhelm Friedrich Herschel in Slough, England (born in Hannover, Germany). Herschel was a musician with the Hanoverian Guards in his youth. During the French occupation of Hanover in 1757 he escaped to England where he became an organist at the spa at Bath. His natural curiosity led him to a variety of intellectual pursuits, among which was observation of the heavens. With little funding, he was forced to grind his own lenses and build the telescopes he needed to pursue his interests. His observations led him to discover the planet Uranus. This drew so much attention that he was given a pension and appointed astronomer to George III. Between 1783 and 1802 he catalogued 2,500 nebulae and star clusters and 848 double stars. He published 70 papers. He founded sidereal astronomy and developed a theory of stellar evolution. He was knighted in 1816 as Sir William Herschel.

August 25, 1900
Death of the philosopher, Friedrich Nietzsche. Nietzsche began his career as a classical philologist before turning to philosophy. In 1869, at the age of 24 he was appointed to the Chair of Classical Philology at the University of Basel (the youngest individual to have held this position), but resigned in the summer of 1879 due to health problems that plagued him most of his life. In 1889 he suffered a collapse and a complete loss of his mental faculties. The breakdown has been ascribed to atypical general paralysis attributed to tertiary syphilis, but this diagnosis has since come into question. He lived his remaining years in the care of his mother until her death in 1897, then under the care of his sister until his death in 1900.

However due to his state of health (liver cancer) the court decided (1993) that he could not be tried. As soon as the decision had been made, Honecker left Germany for Chile where he lived until his death in 1994.
