Historical Note on Euler-Mascheroni Constant
The Euler-Mascheroni Constant was presented by to the St. Petersburg Academy on $11 March 1734$.

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

He subsequently calculated it to $16$ places in $1781$, and published this in $1785$.

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.

In more modern times, published the results of the calculation of its value to $3566$ places in $1963$.

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.
