Opsimathy was once frowned upon, used as a put-down with implications of laziness, and considered less effective by educators than early learning. The emergence of "opsimath clubs" has demonstrated that opsimathy has shed much of this negative connotation.
Notable opsimaths include 19th century army officer and Orientalist Sir Henry Rawlinson, Vivian Stanshall's fictitious character Sir Henry Rawlinson, Grandma Moses, mathematician Paul Erdős (who published papers until his death at age 83), Rabbi Akiva (according to the Talmud he began studying at age 40), and Cato the Elder, who learned Greek only at the age of 80.
