The author seems to be controversial. The Wikipedia entry on him [1] says things like "his reliance on dogma rather than clinical evidence have confirmed his reputation as a controversial figure whose work is seldom cited in modern psychiatric texts.", and others "described him as 'autocratic, a danger, a disaster' and spoke about 'the damage he did'".

"In 1938 Sargant was awarded a Rockefeller Fellowship" says author's wiki. I think this book fits the bill.
