Joseph G. Mccoy helped the cattle industry in Texas develop because he convinced railroads to build towns in Kansas.
Joseph G. Mccoy (1837-1915) was a cowboy and a businessman interested in developing better forms of transportation of cattle from the state of Texas to other parts of the country. Landowners in Kansas did not support the passing of cattle through their lands because they thought that cattle had parasites that provoked the cattle fever and could kill their animals. That is why he convinced railroads to build towns in Kansas to help the cattle industry.
