Henry Steel Olcott
Olcott Estate derives its name from original society president, Colonel Henry Steel Olcott, who formed the society in 1875. During the society's annual convention of 1932, members celebrated the centenary of Colonel Olcott's birth by naming the headquarters campus after him. President Sidney A. Cook referred to the estate as "Olcott" in his annual report. For many years postal mail was delivered to "Olcott, Wheaton, Illinois."
