The building at Rensselaer Polytechnic Institute which houses the Department of Mathematical Sciences is Amos Eaton Hall. It was named after Amos Eaton (17 May 1776 – 10 May 1842,) the co-founder and first senior professor of Rensselaer. wiki/Amos_Eaton_Hall
The Amos Eaton for which the building is named, was the father of Major General Amos Beebe Eaton (12 May 1806 – 21 February 1877.) Amos Beebe Eaton served as a career officer in the US Army and a Union general during the Civil War. So the man for which the building was named was not a Civil War general, but his son was. wiki/Amos_Eaton wiki/Amos_Beebe_Eaton
