There is no LLD in law, it is a JD (Juris Doctor) which I hold.
Prior to 1961 most US law degrees were LLB
American law is the only discipline where a masters degree LLM is higher than the doctorate JD.
Rav Henkin’s other son:Dr. Hillel Henkin PHd was head of the Bureau of Jewish Education in New Haven when I was growing up. He wrote many of our textbooks, workbooks and the curriculum for all Hebrew schools in the community. Dr. Hillel’s wife went to Hunter College with my mother in the early 40s, and was my Hebrew /religion teacher for 5 years.
