French art dealer René Gimpel described him in his diary (1923), as "an excellent American sculptor" who is "very much engrossed in carving himself a fortune out of the trade in works of art." Barnard had a commanding personal manner: "He talks of art as if it were a cabalistic science of which he is the only astrologer", wrote the unsympathetic Gimpel; "he speaks to impress. He's a sort of Rasputin of criticism. The Rockefellers are his imperial family. And the dealers court him."
