I Was Under Oath

Henry Augustus Rowland, professor of physics at Johns Hopkins University, was once called as an expert witness at a trial. During cross-examination a lawyer demanded, "What are your qualifications as an expert witness in this case?"

The normally modest and retiring professor replied quietly, "I am the greatest living expert on the subject under discussion." Later a friend well acquainted with Rowland's disposition expressed surprise at the professor's uncharacteristic answer. Rowland answered, "Well, what did you expect me to do? I was under oath."
