I am the current editor of the Years Ago column for The Mathematical Intelligencer. Years Ago features essays by historians and mathematicians that take us back in time. Whether addressing special topics or general trends, individual mathematicians or ‘‘schools,” analyzing historical research publications or spotlighting mathematical materials found in archives, the idea is always the same: to shed new light on the mathematics of the past. Submissions should be uploaded to submission.springernature.com/new-submission/283/3.
