Seagraves, born in Wilkes County, started with R. J. Reynolds in 1955 as a salesman. By the late 1960s he was a division manager. He attended a 1969 R. J. Reynolds meeting where they discussed how to promote their tobacco with the April 1970Public Health Cigarette Smoking Act prohibiting television and radio advertisements. NASCAR owner Junior Johnson suggested that RJR sponsor his team. Seagraves suggested that RJR should sponsor the entire league. The sponsorship resulted in NASCAR renaming their premiere series from the Grand National Series to the Winston Cup Series. RJR created the Special Events Operations division to find creative ways to promote the tobacco, and placed Seagraves in charge in 1972. After signing the deal, Reynolds had NASCAR founder Bill France, Sr. change the schedule to remove the most of the shortest tracks from the schedule so it could concentrate its marketing on larger crowds at larger tracks. Remaining events were over 250 miles long, and the number of races was reduced from 47 to 31. Seagraves hired apprentice T. Wayne Robertson to take a show car to local events such as shopping malls. Robertson brought along a sign with the current NASCAR points leaders and the location of the next event. Seagraves talked with RJR management and they agree to increase to three show cars on display within 150 miles of the upcoming event to promote NASCAR and Reynolds. Seagraves promoted the product in other sports, including golf, hydroplane racing, soccer, and tennis. RJR sponsored racetracks to upgrade their facilities, notably NASCAR Winston Racing Seriesshort tracks throughout the United States. Tracks were given red and white paint and told to paint their safety walls alternating red and white to give the illusion of greater speed. Some tracks were on the verge of bankruptcy, and the sponsorship helped them and NASCAR survive. He also helped racing teams to find sponsors. In 1982, he urged Piedmont Airlines to become Richard Childress Racing's first sponsor. He retired in 1985. He was succeeded by T. Wayne Robertson.
Death
Seagraves died on September 27, 1998. He was survived by his wife Ardette and son Colbert. Upon his death, NHRA president Dallas Gardner said "Ralph was certainly the patriarch of motorsports' sponsorships, but Ralph's real legacy is that he always considered R.J. Reynolds as a partner in building motorsports, not a sponsor. His contribution to the success of NHRA is immeasurable. We will miss him."
