The world's first skyscraper, the Home Insurance Building, was built in Chicago in 1884. It was only 10 stories tall, but it was the first building to use a steel frame to support its weight, which allowed it to be much taller than traditional buildings made of brick or stone.
McLean County, Illinois, situated in the central part of the state, has a rich history dating back to the early 19th century.

In the early 1800s, European settlers began to arrive, establishing the first permanent settlements in the county.

In 1830, McLean County was officially established and named in honor of Judge John McLean, a U.S. Supreme Court justice.

The town's strategic location along the Illinois Central Railroad further contributed to its growth.

During the mid-1800s, McLean County experienced rapid development, with agriculture playing a crucial role in its economy. The invention of the grain reaper by Cyrus McCormick revolutionized farming practices, and McLean County became known as the "Prairie State's Breadbasket." The county's fertile soil allowed for the cultivation of corn, wheat, soybeans, and other crops, contributing to its prosperity.

In the 20th century, McLean County continued to evolve, embracing technological advancements and diversifying its economy.
