[David O. McKay Office Journal]
The news of [Stephen L Richard's] passing was a terrible shock to me.
May 19, 1959: [Part of telephone conversation between McKay and Ezra Taft Benson:] Brother Benson: It [the death of Richards] is an awful shock, and I know what a shock it is to you! President McKay: He has been as close to me as a brother could be, a friend of the truest kind. He has been wonderful, and of great value to me. It is a great loss to the Church. He was a great intellect, a great soul. He was as loyal to me as his grandfather was to the Prophet and just as close.
