Conrad became the editorial cartoonist at the Denver Post in 1950. While at the Denver Post he first began to draw cartoons about peace and nuclear weapons.  His cartoon depicting the ending of the atmospheric nuclear testing moratorium in 1961 was categorized by Gamson and Stuart (1992) as falling under the universal “Common Security” media frame popularized by the peace movement in the United States.  These types of cartoons emphasized progress towards disarmament and “mutual cooperation, trade, cultural interaction, problem solving, and peacemaking” towards other nations, such as the Soviet Union.He joined the Los Angeles Times in 1964 where he spent the next four decades until he retired. After criticizing president Richard Nixon during the Watergate scandal, Conrad was the only cartoonist to appear on Nixon's Enemies List.  In the 1980s, Conrad criticized the military buildup and arms race advocated by president Ronald Reagan, and the involvement of the Reagan administration in the Iran–Contra affair, the illegal covert operation which sold weapons to Iran to secure the release of hostages while funding the contras in Nicaragua with the proceeds from the arms sales.Conrad later began working as a sculptor, often donating smaller works for fundraisers.  After giving a lecture, Conrad was introduced to philanthropist Joan Kroc, widow of Ray Kroc, the founder of the McDonald's corporation.  Kroc was active in the anti-nuclear movement in the United States and was known as a generous patron of the arts.  After becoming friends with Conrad and his wife,  she anonymously contributed $250,000 to build the anti-nuclear sculpture that would become Chain Reaction.
