Were it not for Jack, I probably would not be teaching at Columbia Law School today. Way back in 1983, Jack, then several years from emeritus status, determined to identify and recruit a prospective intellectual property scholar who would join him in building an IP program for Columbia, and might in the long run succeed him. Jack had read all the articles about copyright published by young scholars and would-be scholars, and then proceeded to contact some of the authors for interviews. The interview led, at least in my case, to an invitation to teach a session of Jack's "Business Torts" class, as the intellectual property survey course was then called.
