The original Kansas City Public Library building was constructed under Greenwood's direction and he was committed to making its services available to the public for the rest of his life. He served on the Kansas City Public School board as a superintendent for nearly four decades. Through his progressive programs and vision, Greenwood became highly regarded in educational spheres. Greenwood is commemorated here in classic portraiture style, frontally posed with a patient expression. He donned a quaint black onyx pennant on his tie for the occasion, suiting his memory as elegant and humble.
