Charles DeLano Hine,
Letters from an old railway official…
(1912)
“ For, my boy, the unit system of organization on the Harriman Lines, of which you have read more or less, is primarily a substitution of the modern chief of staff idea for the grown, dwarfing, irrational government by chief clerks. [1] The unit system of organization requires that an official, whether the head of the unit or an assistant, shall, when absent on the line, be represented at headquarters by the senior or chief assistant of the unit. Such senior or chief assistant is in effect, though not in name, the chief of staff. ”
