Above the farm center’s main doors are four squares bearing the words “STAND TALL. THINK TALL. SMILE TALL. LIVE TALL.” This was a philosophy espoused by Ralston-Purina founder William H. Danforth. After Bill Matthews died, a Purina salesman who worked closely with him told Nelda Matthews, “Bill was a four-square man.” They included Danforth’s words in the stonework as both a nod to a longtime corporate partner as well as in memory of Bill Matthews.
