2008: David Nelson: The Penguin Dictionary of Mathematics (4th ed.):
- division sign
Mistake
- The alternative sign $/$ ... was recommended by William de Morgan in $1845$ to simplify the printing of fractions.
Correction
William De Morgan, born $1839$, was the son of Augustus De Morgan, and as he was aged $6$ at the time, could not have been designing printed material.
It is assumed that Augustus De Morgan himself was meant here.
