Kennedy, left, and Nixon at a CBS television studio in Chicago, Sept. 26, 1960.

The Kennedy camp pushed for the debates, knowing their candidate had much to gain because he had far less recognition nationwide than Nixon did as the current vice president. 

Kennedy and Nixon (both seated) listen to 60 Minutes founder Don Hewitt (C), the producer-director of the first-ever televised presidential debate, during preparations one day before.The first debate between the candidates took place in a Chicago studio of CBS affiliated WBBM. 

Nixon had a slim lead in polls going into the first debate. The candidates held four debates in total, three of them in October. The first in Chicago was the one that left the most memorable impression. The debate is credited by some with swinging a close election in favor of the more telegenic Kennedy.

A key mistake Nixon made in the first debate was wearing a light gray suit which nearly matched the backdrop.

The first debate centered on domestic policy issues. It also marked the beginning of television playing a significant role in politics with 70 million viewers tuning in to watch.

Kennedy, 43, was a first-time senator from Massachusetts. The wealthy New Englander not only lacked Nixon’s experience, but being Catholic was considered a handicap. Just sharing a stage with the vice president put him on an important equal footing.

Mrs. Kennedy, who was six months pregnant with the couple’s second child, hosted a group of Democratic leaders at a television watching parties for each of the four debates.  

Hewitt, who produced and directed the first event for CBS, said that Kennedy prepared more for the debates,“Kennedy knew it was going to be important. He rested that afternoon.” Kennedy came off tan and fit.

Hewitt said, ”Nixon made a speech to the Carpenters Union that day in Chicago -- thought this was just another campaign appearance that night -- was ill. Arrived at the studio, banged his knee when he got out of the car, was in pain, looked green, sallow, needed a shave.”

Mrs. Kennedy’s debate watching parties received considerable attention from the news media.

Vice President Nixon wipes his face with a handkerchief in Chicago, Sept. 26, 1960. His profuse sweating on stage created a poor impression. Nixon came off pale and unhealthy both because he was, in fact, ill with the flu and refused television makeup. In addition, Nixon had recently lost weight while hospitalized for a knee injury. 

Nixon, already known as “Tricky Dick,” was also sporting a 5 o’clock shadow that was highlighted by television lighting. He used LazyShave to hide his stubble, but it sweated off under the hot tv lights.

The next day, the Chicago Daily News ran the headline “Was Nixon Sabotaged by TV Makeup Artists?”

Nixon came off better in the subsequent dates, particularly the fourth and final one on foreign policy in a New York television studio on Oct. 21, 1960. 

Kennedy went on to win the election, however. Impressions made in the first debate stuck. 

Both Lyndon Johnson, in 1964, and Nixon, when he successfully ran again for president in 1968 and re-election in 1972, refused to debate their opponents. The next televised presidential debate didn’t happen for 16 years, until 1976.
