Historical Note on Euler-Mascheroni Constant
The Euler-Mascheroni Constant was introduced by in $1734$.

He calculated it to $6$ decimal places, and published it in $1738$ as $0 \cdotp 577218$ (although only the first $5$ were correct, as himself surmised).

claims that calculated it to $16$ places at some point, but give no further details, and this has not yet been corroborated.

published a calculation to $32$ places of the value of this constant.

Only the first $19$ places were accurate. The remaining ones were corrected in $1809$ by.

There exists disagreement over the question of who was first to name it $\gamma$ (gamma).

Some sources claim it was who named it $\gamma$, in $1781$, while others suggest its first appearance of that symbol for it was in 's $1790$ work Adnotationes ad calculum integrale Euleri.

However, a close study of those works indicates that used $A$ and $C$, and in the work cited,  used $A$ throughout.

An early appearance of the symbol $\gamma$ was by in his $1837$ paper, and this may indeed be the first.
