Crosby is on Farm Road 2100 near the Southern Pacific tracks two miles north of State Highway 90 and just outside the Houston city limits in eastern Harris County. The town was named for G. J. Crosby, a railroad construction engineer. Charlie Karcher opened the first store there in 1865, and the town quickly became a retail and shipping center for lumber and agricultural products from between the San Jacinto River and Cedar Bayou. A post office opened at the community in 1877, and in 1884 Crosby reported a population of fifty, a school, a Baptist church, and a general store. By 1891 it still had fifty inhabitants, as well as a Methodist church, two livestock stables, and a general store. Local legend reports that the community had received the nickname Lick Skillet by 1898. In 1905 it had one school with four teachers and 122 students. There were 300 people in Crosby in 1925 and 600 in 1929, when it became a banking center. Its population fell to 300 during the Great Depression but grew to 750 during World War II and then rose to 900, where it remained for most of the next twenty-five years. Crosby reported fifty businesses and a population of 2,500 in 1976. In the early 1990s Crosby reported 238 businesses and a population estimated at 1,888, though considerably more people lived in the area at that time. In 2000 the population was 1,714 with 455 businesses.
