Clemente’s son, Roberto Clemente Jr., is on the advisory board of the Coraopolis-based company that developed it nearly two years ago, RC21X. The company’s name combines Clemente’s initials and uniform number. Clarence Carlos, chief executive officer and founder of RC21X came up with the idea after the teenage son of a close friend died from brain injuries he sustained playing high school football. Carlos believes the technology his company has developed might have saved his life.
