Law degrees were introduced in the US by the College of William & Mary in 1792, with its "Batchellor of Law" (sic) (L.B.) degree. This was followed by the "Graduate of Law" at the University of Virginia in 1829, which became the first American LL.B. in 1840. The J.D. was introduced by the University of Chicago in 1902, with the same curriculum as the LL.B. but requiring a previous B.A. or B.S. for entry. The J.D. spread, but encountered opposition, and Harvard, which imposed graduate entry as a requirement for its LL.B. course in 1909, and Yale used the name for their post-LL.B. degree, elsewhere called the LL.M. By the 1930s, when most law schools had shifted to graduate entry, the standard degree was once again the LL.B. The second shift to the J.D., again without a change of curriculum, came in the 1960s, with all American Bar Association-accredited professional degrees adopting the nomenclature by 1971.
