1 For most of 1915–1917, Charles P. Berkey was Acting Secretary while Hovey was on an ice-bound exploratory ship off Greenland.
2 James F. Kemp was Acting Secretary during most of 1925 while Berkey was in Mongolia.
3 Aldrich was the first full-time salaried Secretary; he was also Editor-in-Chief from 1934 until his retirement 28 Feb. 1960.
4 This position, with no management responsibilities, was necessary because the bylaws required that the Secretary to the Council must be an elected Councilor.
