In the year 1896 Chaplain Winfield Scott recognized the need for an educational system in the community. For seven months Mrs. George Blount, wife of the principal of the Phoenix School, had been teaching eight children in her ranch home near the Scott Homestead.

On August 3, 1896, a group met with Chaplain Scott to discuss the matter of a school. The Chaplain, Mr. Frank Titus and John S. Tait were asked to serve as a school committee. On August 20, 1896 they met at the Titus ranch and organized the community into a school district. Scottsdale was chosen as the name of the district, to honor Chaplain Scott. Three lots were chosen southeast of what is now Brown Avenue and Main Street. Some of the townspeople erected a 16x18 foot wooden building. The school term opened with fourteen pupils, representing all eight grades. The new teacher, Hattie Green, was paid $45.00 a month. The following August another room was added, extending 12 feet to the north, to accommodate the growing number of pupils. This building was used until 1909, when the increased enrollment made it necessary to increase the size of the building.

A bond election was held May 1909 and a $5,000.00 bond was passed to build a new building adjacent to the original school. It was named Scottsdale Grammar School and now houses the Scottsdale Historical Museum. It contained two large classrooms, an entrance hall, and two small rooms for storage of supplies and books and was erected over a full sized basement.

While the building was being used as a school it was also the center of the social life of the community. It was used for a Sunday school and church, a polling place including the election that decided for a new Scottsdale High School, a Farm Improvement Society, and Red Cross bandage rolling. After the building of Scottsdale High School and a new Scottsdale Elementary School, the brick schoolhouse was renamed the Coronado School and was used as a school for Mexican-American pupils.

The newly incorporated town became owner of the parcel and used part of the building as city offices and rented out part to the county. Thus the "Old Brick Schoolhouse" became the Town Hall and the County Court Office. When the city offices outgrew the building it became the city library.

In 1968 the city was going to tear the building down as part of the Scottsdale Mall development. The Scottsdale Historical Society was formed in 1969 to save the building. They had many fundraising projects to raise money to restore the building. They were not able to raise enough money for restoration.

The Chamber of Commerce then offered to help raise the money needed if they could use the building for their offices until such time as they could get a place of their own. In 1972 the Chamber of commerce signed a lease agreement with the city and moved in.

For a number of years the Historical Society held their meetings in the basement and had a small display area on the main floor.

In 1991 the Chamber of Commerce moved to a nearby building on the Scottsdale Civic Mall. In July, 1991, the Scottsdale Historical Society opened the Historical Museum with displays of old photographs, a classroom as it would have been in 1910, and other displays depicting life in Scottsdale and the southwest.
