The earliest I can find him quoted is August 1925, the same date as the above article.
Here he is in the Stockton Record claiming that one day our ears would become so big that they would receive radio signals directly.
By February 1926, he was now called Dr. E. Pfuffer, and was claiming that New Yorkers should start wearing ear muffs year round to make sure that they did not have mule-like ears in the future.
