===Death===

Tycho died on [[October 24]] [[1601]], eleven days after suddenly becoming very ill during a banquet. He was ill for eleven days, and toward the end of his illness he is said to have told Kepler "Ne frustra vixisse videar!", "Let me not seem to have lived in vain”.<ref>Pierre Gassendi, "Tycho Brahe", 1654, Feynman's Lost Lecture: The Motion of Planets Around the Sun, David L. Goodstein and Judith R. Goodstein [dhttp://books.google.com/books?id=ysZI5NcksUcC&pg=PA28&ots=NJU2NTP1jT&dq=%22let+me+not+seem+to+have+lived+in+vain%22+Kepler&sig=0uK8JpIYDdfzefBUQCB1J8M22fo]  ISBN 0393039188 . For hundreds of years, the general belief was that he had strained his [[Urinary bladder|bladder]]. It had been said that to leave the banquet before it concluded would be the height of bad manners, and so he remained, and that his bladder, stretched to its limit, developed an infection which he later died of. This theory was supported by Kepler's first-hand account.

Recent investigations have suggested that Tycho did not die from urinary problems but instead from [[mercury (element)|mercury]] poisoning: extremely toxic levels of it have been found in his hair and hair-roots. Tycho may have poisoned himself by imbibing some medicine containing unintentional [[mercuric chloride]] impurities, or may have been poisoned. [http://www.tychobrahe.com/eng_tychobrahe/myt.html] According to a 2005 book by Joshua and Anne-Lee Gilder, there is substantial circumstantial evidence that Kepler murdered Brahe; they argue that Kepler had the means, motive, and opportunity, and stole Tycho's data on his death.(Joshua Gilder and Anne-Lee Gilder, Heavenly Intrigue: Johannes Kepler, Tycho Brahe, and the Murder Behind One of History's Greatest Scientific Discoveries, ISBN 978-1-4000-3176-4 )  According to the Gilders, they find it "unlikely" Tycho could have poisoned himself since he was an alchemist known to be familiar with the toxicity of different mercury compounds.
