Who is Dr. Anthony Horvath from The Mote in God's Eye and what is their importance?

Dr. Anthony Horvath is minister of science to New Scotland and not a member of the nobility. He is a professional administrator with years of experience getting what other scientists need so they can do their work. Horvath is also quite narcissistic, though well-intentioned. He will be the lead scientist on MacArthur for her scientific mission to the Motie system.
