I just came across this story discussing a presenation that my father gave a while back at BYU. One writing professor had this to say:
He has such knowledge and such depth, and he can explain things in ways that make it absolutely clear to everyone, and in ways that are both erudite and humorous both at the same time. Richard Oman is one of the most fascinating people in the world to listen to. He’s one of those people who leaves you thinking for weeks afterwards thinking about what he said.
