A petition for Charter under dispensation was granted to St. John’s Lodge #19 on September 3, 1849 - St. Johns Lodge #19 was chartered on June 6, 1850.  The Brethren surrendered the Charter in June of 1855.  Eureka Lodge was chartered under dispensation on April 3, 1856.  The Lodge name was changed to Lyons Lodge #93 and a Charter issued on June 3, 1857.  The Lodge was initially located on the corner of Grant Street and 25th Avenue North in Clinton, Iowa.  A fire destroyed the building on September 28, 1870.

The Lyons Masonic Temple Association was formed in 1870 and a four story building was erected on February 21, 1872, at 63 - 65 Main Avenue in Clinton.  Lyons Lodge #93, DeMolay Consistory, and the Royal Arch Chapter occupied the 2nd, 3rd and 4th floors of the building while the first floor was rented to retail merchants.

Lyons Lodge #93 moved to 94 Main Avenue in Clinton, and the building was dedicated on January 13, 1932.  The mortgage was retired in 1946 and the building remains occupied by the Blue Lodge.

Br. William E. Leffingwell PM was the first Worshipful Master of Lyons Lodge #93.  in 1857.  The Lodge has produced two Grand Masters of Iowa Masons:

On April 28, 2007, Lyons Lodge #93 celebrated 150 year Sesquicentennial Rededication under the guidance of Br. Howard Neese II, PM [2002, 2007] and Br. David Spooner, PM[1976], District Lecturer. 

“ Masonry in Clinton today is symbolic of the mighty fraternity that is strong and stately.  Our duties are yet completed. Our roots have grown deep, built on an unshaken foundation.  This giant superstructure which represents 150 years of Masonry was begun by our early brethren who worked unceasingly and untiringly with courage, zeal, and determination.  Had not this endeavor from the very beginning received but the finest care and attention of its craftsmen through these past decades, had they not spread the finest cement with the Mason’s Special Tool, our fraternity today would not be as universally recognized by its strength and witness of its renowned philanthropically benevolence

The future of Lyons Lodge #93 will continue to be progressive, in its growth in the hands of the brethren, who will continue to rise stately and magnificently if we do not deviate from the laws so earnestly recommended by the Masonry’s progenitors.

If Br. Leffingwell was here today on this memorable occasion and could see to what proportions his Lodge has grown from its small beginnings when he first presided over it, he would be pleased in glad for the part he took in its inception.”
