In the 80s I used to go to Merrill Lynch’s employee cafeteria at their main headquarters in NYC most lunch times and play chess there. There was a young guy named Brian McCarthy who was a USCF master who worked in the mail room at Merrill and who occasionally played in the cafeteria at lunch time . I suspect it is probably the same Brian cited here and he was working his way through college at the time. Very sorry to read this
