Certainly the most famous person who got his start on the Hoot Owls was Mel Blanc.
On June 23, 1923 Mel was first featured on the KGW program Stories By Aunt Nell from 3:30 to 4pm. The Oregonian described it as: For the entertainment of the children, this afternoon Melvin Blank, a boy with a good voice, will sing a number of solos, accompanied on the piano by his brother. Aunt Nell will read additional chapters from Allen Chaffees story of Sitka, The Snow Baby. Children love the story of the little Polar cub and his adventures and messages come in daily asking for another story about him.
