In 2008, All Saints Catholic School celebrated its Golden Anniversary. It had been 50 years since the school opened in 1958, and with over 700 graduates, All Saints put on a big celebration recounting its history and everything that had happened over the last 50 years.

In March 1993, All Saints School began its effort toward having the school accredited. In the 1990s, many private schools were going through the accreditation process, which demonstrated that they deliver a quality education and meet certain educational standards. 

In the early 2000s, as All Saints School continued to grow the classes and programs offered to its students, space became an increasing concern. The school, which was built for the needs of a robust mid-century student body, was simply inadequate to meet the needs of increased programs and technology of the 21st Century.

Throughout much of the history of Catholic education in the United States, classes were taught almost exclusively by religious sisters. Many religious orders existed whose main purpose was teaching.

In an effort to strengthen the relationship between families and the school, All Saints School formed a Home-School Association in October 1973. 

All Saints School can trace its history back to February 5, 1950, when a parish meeting was held at All Saints. It was at this meeting that the congregation decided to raise the yearly church dues from $21 to $31 per family to start a fund for a parish school.

When the new Denmark Middle School opened in 1993, it gave the other schools much-needed room. 

Throughout the latter half of the twentieth century, rail service began to decline.  Passenger rail service dropped off significantly, and freight declined, as well, owing to the ease of transporting goods by truck and airplane. The Chicago & North Western Railway that ran through downtown Denmark was once a bustling line with multiple passenger trains a day.

Very few airplanes, if any, ever make their way to Denmark. That changed in 1957 when Denmark was visited by a pilot traveling through the area.

After World War II, one-room school districts began a general decline as people increasingly moved from rural areas to villages and cities. Because the one-room school districts were falling well below capacity, a movement began to consolidate the thousands of small school districts throughout the state into larger, more efficient districts centered around the local high school.

In 1914, St. James Catholic Church and School in Cooperstown were destroyed by a fire. While several items from the church were able to be saved, the buildings were total losses. Despite the significant setback, the congregation resolved to rebuild.

In 1960, All Saints Parish hosted a regional Holy Name Rally bringing thousands of people to Denmark for an hour of prayer.

In 1916, Steve Siudzinski began operating the Langes Corners Cheese Factory, which later became known as Steve’s Cheese. As Steve’s business grew and modernized, a new and larger cheese plant became necessary.

In 1918, only three years after the Village of Denmark incorporated, the village constructed its first sewage treatment system. The initial system consisted of an Imhoff tank housed in a “barn-like structure hidden in the woods”. The Imhoff tank functioned much like a septic tank doing “little more than [removing] solids from the liquid sewage”.

During the 1950s, the Denmark School District worked on projecting their enrollment growth over the next several years to plan for the future. They realized that by 1960, the area would experience a lot of population growth which would translate into a 20-30 percent increase in the incoming freshman classes in the high school.
