As Moline developed in the 1850s, factories and mills were built along the Mississippi River where transportation and water power was readily available. The settlers homes and a small commercial district wre built in the area that is now referred to as Moline's downtown.

The man with the single greatest influence on the destiny of Moline was John Deere. In 183[7], this young blacksmith devised the first steel plow in Grand Detour, Illinois. Demand for the plow was so great that it warranted opening a factory in Moline in 1848. His factory enriched the ethnic mix of the community by attracting workers from Sweden, Germany, France and Belgium.

John Deere's daughter, Emma, married Stephen Velie. Their son, Willard Lamb Velie, Sr., started the Velie Carriage Works, which later became Velie Motors. Before the company was dissolved in 1929, Moline rivaled Detroit in Automobile production.

Twelfth Street hill was the first major hill in Moline to be paved with bricks opening up the bluff for development. Owners of these new homes came from all walks of life. Many were successful businessmen who could afford more spacious accommodations for their families. The mansions of the early industrialists survive chiefly along 11th Avenue, referred to as Millionaire's Row or Deere Row. The reference to Deere in the latter name is quite evident as many family fortunes were tied to Deere & Company.

The area has been enjoying a rebirth in the past few years as Quad Citians rediscover the area. Many have purchased homes and begun restoration, smitten by the rich interior amenities and charm only an older home can offer. The Overlook Historic Neighborhood Association, formed in 2001, has taken the lead in the revitalization process and promoting community awareness of the neighborhood.
