You found two excellent scholarly books to use along with other relevant sources. You still need another *scholarly* source though (academic journal article or book). The biographical sketch in the Willard and Livermore book will be very useful but it's not a scholarly source. The fourth source you list had incomplete information; please fill that in to clarify, and be sure to follow Chicago citation style throughout. Clio.at.work (talk) 01:09, 9 November 2020 (UTC)
