An initial attempt to rename the LL.B. to the J.D. in the US in the early 20th century started with a petition at Harvard in 1902. This was rejected, but the idea took hold at the new law school established at the University of Chicago and other universities and by 1925 80% of US law schools gave the J.D. to graduate entrants, while restricting undergraduate entrants (who followed the same curriculum) to the LL.B. Yet the change was rejected by Harvard, Yale and Columbia, and by the late 1920s schools were moving away from the J.D. and once again granting only the LL.B, with only Illinois law schools holding out. This changed in the 1960s, by which time almost all law school entrants were graduates. The J.D. was reintroduced in 1962 and by 1971 had replaced the LL.B., again without any change in the curriculum, with many schools going as far as to offer a J.D. to their LL.B. alumni for a small fee.
