“…Alexander, 1900; Imbrie and Imbrie, 1979; Tasch, 1986; Farrow, 2001; Gribbin and Gribbin, 2001; Fleming, 2006; Hilgen, 2010; Finnegan, 2012; Sugden, 2014; Pearce, 2018; Dry, 2019). In the year following the bicentenary of his birth, and drawing upon archival records and recently published observations (Edwards 2021a), this paper explores selected aspects of Croll's biography, his scientific connections and controversies, and that area of his life relevant to Quaternary science. While presenting material that has often been ignored hitherto, the paper does not set out to be encyclopaedic, and beyond contextualisation no attempt is made to explain at length the science with which Croll was engaged.…”
