Tycho Brahe to be exhumed

A November exhumation is planned to try to discover the true cause of Tycho Brahe's death. Since a 1901 analysis discovered mercury in a sample of his beard, some have believed the astronomer, "more famous in death than he ever was in life," was murdered.

One theory casts rival scholar Johannes Kepler for the part of the killer, while a less dramatic possible explanation is that Brahe expired from a kidney infection. Whatever the results, the post-mortem will provide valuable details about his manner of life.
