For many years, an open house was held in June, allowing citizens to admire the work of the students in woodworking, drafting, foundry, printing and pattern-making.

In 1902, a gymnasium featuring a swimming pool, opened on the high school campus, and an adjoining tract was purchased for use as an athletic field.

One of the first student projects of 1926 was a student-led bond drive to raise funds to build a stadium to the east of Hackley Field.

On October 21, 1929, a bronze sculpture honoring Hackley was unveiled on the Muskegon High School campus.

On the right side of the memorial is a relief of Mercury, the god of commerce, designed to symbolize Hackley's connections to industry.

To the left is carved the Good Samaritan, the symbol of charity, meant to represent Hackley's role as benefactor to the school district and the city he loved.

Muskegon High School's band program earned national recognition under the guidance of William Stewart, who arrived as a teacher in 1936.

The Hackley Manual Training School was torn down in 1962 as the expense to bring the building up to modern safety standards were deemed excessive.
