  8. See “Technology in Mary Baker Eddy’s Household,” 18 December 2012, https://www.marybakereddylibrary.org/research/technology-in-mary-baker-eddys-household/ We don’t know the exact details of the first typewriter used by Eddy’s staff. But a letter to Calvin A. Frye dated October 31, 1888, from a dealer of inking attachments for Hammond typewriters, ended with the line “will you please allow me to put one on your Type-Writer?” (J. W. Tallmadge to Calvin A. Frye, 31 October 1888, IC989.98.001). So Eddy’s household clearly had owned a Hammond typewriter prior to that time.
