Ben Masselink in "Gene" in Edgar Tafel, ed.,
About Wright: An Album of Recollections by Those Who Knew Frank Lloyd Wright. New York: John Wiley, 1993, pp. 189-190—
Gene [Masselink, his brother, an apprentice to Wright] had driven Mr. Wright in that open Cord down the rolling green hills of Wisconsin and along the sweeping outer drive of Chicago and through the smoky war of Gary, Indiana, and up along the huge, blue lake through Benton Harbor and Saugatuck, Gene's old art school, and into Grand Rapids to see the dentist, who was my dad. Mr. Wright wanted every tooth in his mouth pulled, which could compare to storming the Great Wall of China single-handed, and in one sitting, and then to be fitted for false. This greatly impressed my dad, as this was never done; it was too hard on the patient. Usually, one or two teeth were pulled at a time, four at the most, but Mr. Wright insisted, and so my dad pulled them as if he were plucking corn off a cob. Mr. Wright never flinched, but treated it as casually as if he'd come to have a hair trim.
