Lanitow Irizal was a native of the planet Altair VI who served as director of the Federation's Bureau of Interplanetary Affairs in the 2290s decade.
In the year 2293, Irizal, on the advice of Federation President Ra-ghoratreii, arranged a meeting with Captain Spock in his office on Rigel IV, in the hopes of getting Spock to become a Federation ambassador-at-large. After showing Spock the sort of scenarios he would deal with as an ambassador, he finally accepted. (TOS - Crucible novel: The Fire and the Rose)
