Who Has the Record for the Length of Time Between Date of Last Post-Graduate Degree and Appointment to Tenure Track Law Professorship?

Another superannuated law professor and I (see picture, right) were comparing notes on who held the record (let's limit this to those presently appointed or pending appointment) for the most years between the last post-graduate degree (J.D., Ph.D. or other) and first appointment as a tenure-track law professor (not adjunct or visiting). Full disclosure: I believe I am in the running.

Nominations will be accepted as comments to the post.
