Awards and honors

As an undergraduate, Rubin was named a Putnam Fellow on four occasions, the first time in 1970, aged 14, making him the youngest Fellow to date. In 1972, he tied for third place in the first USA Mathematical Olympiad. In 1974, Rubin was the subject of an article in the '' Madison Capital Times'', in which his Caltech undergraduate advisor was quoted as saying that someone of Rubin's ability appeared in the United States "about once in every ten years".Alternate Link
