Wink began in 1926, when oil was discovered in Hendrick oilfield in Winkler County. By mid-1927, the Wink Townsite Company was selling lots in Horse Wells pasture of the T. G. Hendrick Ranch. The oil boom brought new people to Wink, causing a shortage of housing. Newcomers set up tents and built makeshift houses. Wink was originally named Winkler, Texas, for the county. When a post office was requested, postal authorities notified the applicant that a post office bearing that name already was in operation. The citizens shortened the name to Wink and received a post office in 1927. In that year, the first public school was organized, and a temporary building was constructed. A Sunday school was started by November 1927, and the population of the town was reported at 3,500. By 1929, that number climbed to 6,000. The actual population could have been around 10,000 to 25,000 people.
