H. O. Hartley (born Herman Otto Hirschfeld, but widely know as HOH) was the 74th President of the ASA. He was a remarkable man. He had an interesting and productive life, from his early years in Germany during the rise of the Nazis to his most statistically productive years in the United States. I had the privilege of taking graduate classes from him; to have written my dissertation under R. R. Hocking, who is one of his students; and to be his faculty colleague and successor as head of the Statistics Department at Texas A&M University. For this article, I will use two sources that are still available in the ASA literature, namely, Hartley’s presidential address that was published in JASA and his obituary in The American Statistician
