King was instrumental in the passage of the Iowa Band Law in 1921, which allowed cities to levy a local tax for maintenance of a band.
He was given a testimonial dinner for 250 people in 1951 at the age of 59 where band world luminaries including Glenn Cliffe Bainum, Albert Austin Harding, Paul V. Yoder, and William H. Santelmann attended (as well as William S. Beardsley, the governor of Iowa).
