Enjoy this short but entertaining look at “Benjamin Franklin – the first American ergonomist?” by Dr. John Senders (who has appeared previously on this blog).
Professor Chaplin states of Franklin (p. 65): Cato Major, or His Discourse of Old Age (1744). Franklin solicitously printed the book in large type so that elderly readers (beyond the help even of spectacles) ‘may not, in Reading, by the Pain small letters give the eyes, feel the pleasure of the mind in the least allayed.'”
Enjoy poking around the HFES archives, as well!
