Mandrake, the Magician
How It Got on the Air
The road to the Mutual network ran straight through a bread company. Producer Henry Souvaine — a composer and radio veteran who was simultaneously running Metropolitan Opera broadcasts — brokered the rights sale from King Features Syndicate to the Campbell-Ewald advertising agency of New York. Campbell-Ewald represented Purity Bakeries of Chicago, the parent company of Taystee Bread, and Taystee became the show's sponsor when it debuted on WOR on November 11, 1940. On that same premiere date, Purity Bakeries rolled out newspaper ads, posters, display advertising, and a special Mandrake the Magician bread wrapper. It was a coordinated commercial launch unusual in its scale for a children's Adventure serial.
The property itself was well established. Lee Falk had launched the Mandrake comic strip on June 11, 1934, with artist Phil Davis handling the illustrations while Falk scripted; Davis would work on the strip until his death in 1964. By the time Souvaine brought the show to radio, Mandrake had been a fixture of newspaper comics for six years, and the character had a ready-made audience in the age group Taystee most wanted to reach.
Affiliate stations WLAC in Nashville and Memphis and KWK in St. Louis joined the Mutual run on November 18, 1940, one week after the WOR premiere. The show aired three times a week at 5:30 in its first year, then shifted to weekday afternoons at 5:15 after 1941. Each episode ran fifteen minutes — standard for the juvenile adventure serial format of the period.
The World Mandrake Lived In
The radio Mandrake drew directly from Falk's comic strip mythology. He was a mystic educated in Tibet by a master of magic, living in what the show called a "house of mystery and many secrets." His magic was invoked through the Latin chant invoco legem magicarum — "I invoke the laws of magic" — which set his full arsenal of tricks into motion. By the time the show reached the air, the wartime context had colored his adventures sharply: many of his adversaries were agents of Fascism and Nazism, and storylines regularly put him up against saboteurs and enemy submarines. The master criminal Barracuda was a recurring villain, and a major story arc built around the submarine crew of Captain X ran across multiple episodes in early 1941.
Alongside Mandrake traveled a small but fixed group of companions. Lothar, described in the show as a giant capable of ripping a crocodile's jaws apart or breaking the back of an anthropoid ape, served as his muscle and loyal servant — a characterization drawn straight from the early comic strips, where Lothar appeared in a fez and leopard skin. Princess Narda accompanied them as well, along with a boy companion referred to at various points as Tommy or Jimmy, and a cast member identified as Laddie Seaman.
The Cast Behind the Characters
Raymond Edward Johnson played Mandrake across the entire run. Johnson, born in Kenosha, Wisconsin on July 24, 1911, had started his working life as a bank teller before studying acting at the Goodman School of Drama in Chicago. His early radio work included a regular role on Edgar A. Guest's dramatic serial Welcome Valley and dramatic sketches on The National Farm and Home Hour. In Chicago he began working with writer-director Arch Oboler on the Lights Out series, and when both men moved to New York, Johnson appeared in numerous episodes of Arch Oboler's Plays, including the title role in "The Ugliest Man in the World" — broadcast five times — and as Tchaikovsky in "This Lonely Heart," both from 1939.
Johnson was still playing Mandrake when he began hosting Inner Sanctum Mysteries in 1941, introducing himself as "Your host, Raymond" and earning a following for his chilling episode closings. He left Inner Sanctum in May 1945 to serve in the U.S. Army. In later decades Johnson dealt with multiple sclerosis, which progressively curtailed his broadcasting work, though he remained a presence at old-time radio conventions into his later years, sometimes performing from a portable bed or wheelchair. He died on August 15, 2001, in Wallingford, Connecticut, shortly after his 90th birthday.
Juano Hernandez brought Lothar to life in a career that had already taken him through circus acrobatics, professional boxing under the name Kid Curley, vaudeville, and radio scriptwriting. Born in San Juan, Puerto Rico on July 19, 1896, Hernandez was Afro-Puerto Rican, and the range of roles he played on radio was wide enough to include Benito Mussolini, Chiang Kai-shek, and Haile Selassie I — a breadth he reportedly achieved by studying Shakespeare in his spare time to refine his diction. On Mandrake, Lothar's speech was written in a pattern similar to Tonto's on The Lone Ranger, a reflection of period conventions for the character type. Hernandez also co-starred in radio's first all-Black soap opera, We Love and Learn, and appeared on The Shadow, Tennessee Jed, and Against the Storm. Film historian Donald Bogle has credited Hernandez's early visibility as helping to open Hollywood doors for Black actors, including Sidney Poitier.
The role of Princess Narda was shared by two actors during the run: Francesca Lenni and Jessica Tandy. Tandy — born June 7, 1909 in England — arrived in the United States in 1940 and, with Broadway largely unavailable to her due to restrictions on immigrant performers, turned to radio work. A 1994 Time magazine obituary noted that she worked "on radio as Princess Nada in the serial Mandrake the Magician" among her first American engagements. The Mandrake credit came years before Tandy won the Tony Award for A Streetcar Named Desire in 1948 and decades before her Academy Award for Best Actress for Driving Miss Daisy in 1989.
The Sponsor's Machine
Taystee Bread did not simply buy airtime and wait. The sponsorship came packaged with a listener engagement campaign built around the Mandrake Magicians Club, which children could join through Taystee Bread purchases starting in the spring of 1941. Over WOR alone, the club enrolled 300,000 members within three weeks of the show's launch — a number that reflects both the marketing push and the show's early ratings performance. Within its first ten weeks, Mandrake, the Magician had reached first place in the New York market.
The promotional machine also included a tie-in publication called Mandrake Adventure, issued weekly. The show broadcast a "magic password" that listeners could take to their grocer to exchange for free illustrated leaflets telling the story "Mandrake and the Jungle Giants." The combination of club membership, bread purchases, and weekly story leaflets gave Taystee a continuous presence in the routine of the show's young audience throughout the week, not just during the broadcast itself.
After the Mutual Run
The Mutual network run ended on February 6, 1942. That same spring, the show was revived on New York station WINS beginning March 23, 1942, airing three days a week. Meanwhile, Henry Souvaine had moved to offer 156 of the 195 recorded Mutual episodes for regional and local syndication across the United States and Canada. The transcribed episodes turned up on a scattering of local stations over the next several years — WISN in Milwaukee three days a week from January to April 1943, WHIZ in Zanesville from May 1945 to April 1946, KGER in Long Beach from June 1945 through December 1946, and KGO in San Francisco five days a week from October 1945 with Mother's Cake and Cookie Company as the local sponsor. The serial, even after the network run closed, had a longer broadcast life than its two-year Mutual tenure suggests.
Of the 195 episodes produced, roughly 30 survive in known collections — a small fraction of the total run. The first broadcast from November 11, 1940 is among them, as are episodes from the Captain X submarine arc running through early 1941. In 1973, George Garabedian Productions issued a commercial recording, Mandrake the Magician Original Radio Broadcasts, making a portion of those surviving episodes available in packaged form. The bulk of what was recorded, however, has not surfaced.
