“Two biographical studies of Salt exist, the most reliable being George Hendrick’s Henry Salt: Humanitarian Reformer and Man of Letters (1977). This work seeks to introduce Salt to new readers, a task which is unfortunately still necessary. Hendrick also reprints a number of unpublished letters written by and addressed to Salt. Stephen Winsten’s Salt and His Circle (1951) is made and marred by its association with G.B. Shaw, who wrote a preface for it at age 95 (!) and provided other materials in remembrance of his friend. Winsten’s penchant for imagined dialogue and undocumented conjecture makes one appreciate the obsessive answerability of the best modern biographies.” — William Stroup of Keene State College
To the above we would add that the precious few bits of worthwhile information that can be gleaned from Salt and His Circle are picked up by George Hendrick in his Henry Salt.
