An Independent Mind: The Rebbe Speaks with Prof. Paul Rosenblum
The Rebbe tells Professor Paul Rosenbloom: “I had a younger brother who passed away many years ago. He left this unfinished mathematical paper. If you will supervise someone to prepare it for publication, I will be very happy to pay for it.”

Is it possible that there is a mistake in the subtitles? I thought I heard the Rebbe say, (2:57) "He was very Zealous about his independence", but the subtitles say, "He was very Jealous about his independence".
No, the Rebbe said Jealous.
