Mathematician:Lorenzo Mascheroni

Mathematician
Professor of mathematics at Pavia.

Wrote Geometria del Compasso, published in $1797$, in which he showed that any geometrical construction that can be made with compasses and straightedge can also be achieved by using only compasses.

This had, however, already been demonstrated by in $1672$.

Published in his $1790$ work Adnotationes ad Calculum Integrale Euleri a calculation to $32$ places of the value of what is now known as the Euler-Mascheroni Constant.

However, only the first $19$ places were accurate. The rest were corrected in $1809$ by.
