“Most children like to collect things. At four I started to collect documents of my own development as correlated with world patterns of developing technology. Beginning in 1917, I determined to employ my already rich case history, as objectively as possible, in documenting the life of a suburban New Englander, born in the Gay Nineties (1895)– the year automobiles were introduced, the wireless telegraph and the automatic screw machine were invented, and X-rays were discovered; having his boyhood in the turn of the century; and maturing during humanity’s epochal graduation from the inert, materialistic 19th into the dynamic 20th century. I named my documentation the Chronofile.
