Tom is a character in the movie Interstellar. He is Coopers son and Murphys brother. In the movie, Tom was stubborn with his sister Murph when she told him that his wife and son were dying from respiratory illness brought on by the dust storms. He refused to leave his farm and go to NASAs underground facility. Later, Cooper and his team leave Earth on a mission to find a new habitable planet. Tom is not mentioned much in the movie after this point. In one of the recordings, Tom mentions that they buried his granddad out in the back forty next to Mom and Jesse. It looks like Tom’s son Jesse died from something unknown, but it’s logical to assume it resulted from what was happening to Earth. It is likely that Tom passed away a while back because of the epidemic resulting in a variety of diseases. In the film, we are told that Tom’s wife and son have developed some kind of respiratory disease because of the dust in the air. It’s likely that they all eventually died of it. Cooper doesn’t look for him in the Cooper Station, indicating that Tom passed away a while back because of the epidemic resulting in a variety of diseases.
