The Freemasons must be credited with a movement, inaugurated at this time, which was to have a far-reaching effect. The meetings of Lodge No. 45 in the taverns had been conducive of almost everything except sobriety. The effects were degrading, and in many cases injurious, not only to the persons affected but to their dependents as well. Also the evil was growing, and was contrary to the expressed ideals of the order. Practically all the leaders in the village, whether in public or private life, had been or were still members of the lodge. Among the older members were General Richard Butler and his brother, Colonel William Butler, General John Neville, Judge Hugh Henry Brackenridge, Captain Joseph Ashton, John Ormsby, Colonel James O’Hara, Captain Michael Hufnagle, Major Isaac Craig, Senator James Ross, Samuel Ewalt, and Captain John Irwin. Younger members were Dr. Andrew Richardson, Dr. Hugh Scott, William Wusthoff, Anthony Beelen, Thomas Baird, James Riddle, Tarleton Bates, Rev. Robert Steele, and Henry Baldwin. It is not surprising that such men should sooner or later realize the calamity which confronted the members of the lodge, and decide upon eliminating the cause. The change was effected upon the completion of William Irwin’s brick house, at the southwest corner of Market Street and the West Diamond, just prior to the opening of the new century. Thenceforth the meetings of the lodge were held in a room on the third floor of this building, and the temptation to excessive drinking was at least farther removed than when the sessions were being held in the “Sign of the Green Tree.” This was the first practical temperance movement in Pittsburgh. Market Street was one of the narrowest streets in the town, but was the principal commercial thoroughfare. Coincidentally it was called “Main Street.” It received the name by which it has been known for more than a century and a quarter, from the fact that the first market house, erected in 1787, was located at the northwest corner of this street and Second Street. In 1800 the street was bustling with life. More drays and carts and wagons were moving over at least a portion of the thoroughfare than is the case to-day. Intermingled with the other vehicles were wagons from the country, drawn by oxen. In wet weather the roadway was ground into mud and thin mire. The merchants generally lived with their families in the houses where their business was conducted. The street was noisy with children. Trees grew on the outer edges of the foot-walks, and in the summer grass and weeds sprang up, watered by the street wells and pumps that supplied the residents with water.
