Early in 1850 the Grand Royal Arch Chapter of the State of Illinois was organized. On Christmas day of that year the companions of Euclid Lodge No. 65, A.F. & A.M. petitioned the Grand Chapter through Chicago’s Lafayette Chapter No. 2, a Royal Arch Chapter.

The Local Chapter held meetings that first year under the guidance of the Grand Chapter.

Its Charter was granted October 3, 1851 and on November 11 of that year the first regular meeting of the Chapter was held. Aylmer Keith was elected the first High Priest. The other officers were: John Eddy, King; Harry T. Wilson, Scribe; Nahum Loring, Captain of the Host; V.W. Potter, Principal Sojourner; Russell Whipple, Royal Arch Captain; John Bolton, Master of the 3rd Veil; Zadoc Hall, Master of the 2nd Veil; Ezekial Hall, Master of the 1st Veil; Henry L. Peaslee, Treasurer; Cheney M. Castle, Secretary; Joseph Naper and Calvin C. Barnes, Stewards; and Charles N. Fox, Sentinel.

The Chapter voted the following year to take stock in the Naperville Academy to the amount of $100.00. The Blue Lodge and the Odd Fellows joined with them in doing the same and the upper room of the Academy was then completed as a union hall where meetings were held.

Later Chapter meetings were held in Captain Naper’s store and of course, the Masonic Hall which was formerly the second story of the present City Hall building.

Four other Chapters - Aurora, Joliet, Wheaton, and Downers Grove - petitioned the local Chapter to recommend them to the Grand Chapter for dispensation for Charters.

Today, Euclid Chapter No. 13 is comprised of about 55 Companions, the majority of them also being members of Euclid Lodge No. 65.
