Gordon Rosewater is often credited as the man responsible for the construction of Paradigm City, and the original founder and chairman of the Paradigm Corporation. Gordon's son, Alex Rosewater, took over his father's duties when he retired. Gordon spends much of his time in a private dome of his own, growing tomatoes and wheat.
Gordon appears to be perfectly content with the uncertainties of the past, much to the dismay of those who come to him for memories, including Alex. While many look to him for answers, Gordon typically appears to be rather senile, or at least very apathetic. However, his odd speeches about his tomatoes appear to actually be a cryptic euphemism to answer the question. He gives Roger several clues to the past.
Roger Smith has a recurring flashback of a man in a bloodstained surgeon's uniform standing before a group of children, and Roger believes this man to be Gordon Rosewater, implanting memories of the past into a younger generation. Gordon refuses to comment on this accusation directly, but, referring to his tomato crop, states "these tomatoes are reproduced synthetically, with only the memories of the sweet flavor from the original. If we keep repeating the process, this fruit will eventually become the real thing." He does not appear to have actually lost any of his memories however, as he has moments of apparently random lucidity throughout the series during which he reveals important clues to the Event. At the end of the series, he apparently regains both his mind and his interest in the city's past, explaining to Roger, Angel, and Vera several important truths about Paradigm and each of their various existences.
