    Description

    Robert Simson Autograph Letter Signed "Rob: Simson" (1687-1768). Three pages, 7.25" x 9.25", Glasgow, June 11, 1760. Simson comments on another mathematician, discusses Euclid, and mentions his forthcoming edition of Data, in part: "the Data will be longer than what we have in the former editions...the book shall be sold at 5 or 6 shillings, tho I should be a loser by it..." A British mathematician and professor of mathematics, Simson is known for his criticisms and commentaries on the ancient geometers, specializing in Euclid. His Euclid's Element was long the standard Euclid text in England. The pedal line of a triangle is sometimes called the Simson line after him. Our research shows no record of a sale of any Simson autograph material in recent years. This is a special opportunity to own a content letter from a legendary geometer. Having a paper conservator repair the fold splits and clean the light soiling would make this letter worthy of display in any fine collection or museum.

    Also included is a 1776-dated engraving of Simson in excellent condition. From the Henry E. Luhrs Collection. Accompanied by LOA from PSA/DNA.

    The pre and post sales experience was wonderful and flawless. Heritage has the best in-house operation I have ever seen and their people are not only professional but fun to work with, especially Steve C.

    As for Heritage's online system… Yes the interface is more complex than what we are used to with SAN but what is behind that interface is amazing for sellers and buyers alike. It is real time and for a real serious auction buyer there is nothing better in the auction industry, bar none.
