Johann Rahn

Johann Rahn〔The dictionary of biographical reference By Lawrence Barnett Phillips. pg (775 )〕 (Latinised form Rhonius) (1622–1676) was a (
* 10 March 1622 Töss (Winterthur), † 25 May 1676 in Zurich) Swiss mathematician who is credited with the first use of the division symbol, ÷ (obelus)〔Such as on pg 16; Teutsche Algebra. (Pg 16 )〕 and the therefore sign, ∴.〔Such as on pg 53; Teutsche Algebra. (Pg 53 )〕 He is known for his Teutsche algebra, the first time the Geteiltzeichen characters appear in print. The symbol is used in ''Teutsche Algebra'', published in 1659. John Pell collaborated with Rahn in this book, which contains an example of the Pell equation, Pell-loading of the English translation of the book of Rahn. There is a controversy in Pell awards, rather than Rahn, authorship notations. Rahn was also, it seems, mayor of the city of Zurich in 1655.
