While in Omaha, he taught undergraduate journalism classes at Creighton University where he was exposed to frequent, lengthy political debates between conservatives and liberals alike.
An old Jesuit at Creighton recommended him to some former students in New York and Sidey landed a job with Life magazine where he made an immediate impact.
Sidey correctly guessed that something was amiss when in 1966 he saw the fastidiously dressed President Lyndon B. Johnson wearing brown shoes with a gray suit.
Johnson then flew to Vietnam for a surprise public relations visit later that day.
Sidey died of an apparent heart attack while vacationing in Paris at the age of 78.
