The Birth of Mr. Jack

Mr. Jack: The Pioneering Playboy Tiger Who Shaped Comic Strip History

Jimmy Swinnerton, the creator of Mr. Jack, embarked on his career as a young illustrator for the San Francisco Examiner, a newspaper owned by the influential William Randolph Hearst. It was in 1893 that Swinnerton’s artistic talents were first showcased, as he drew adorable bear cub illustrations for the paper. These illustrations accompanied the newspaper’s coverage of the San Francisco Mid-Winter Exposition of 1894, captivating readers with their charm.

After the exposition, Swinnerton continued to feature his beloved bear characters in the newspaper, this time in association with the weather forecast. These bear cartoons grew in popularity, leading Swinnerton to create a regular feature called “The Little Bears,” which commenced on June 2, 1895. Significantly, this marked the birth of one of the earliest American comic strips with recurring characters, setting a precedent for the genre.

A Shifting Focus

Swinnerton’s creative genius did not go unnoticed within the Hearst newspaper chain. In 1898, at Hearst’s request, Swinnerton relocated to New York City to work on cartoons for the New York Journal. Here, he transitioned his characters from bears to tigers, the emblem of Tammany Hall, a significant political organization of the time. This marked the inception of “The Little Tigers,” a comic strip that debuted on February 20, 1898.

Initially, “The Little Tigers” featured fairly generic characters. However, distinctive personalities emerged, the most notable being the womanizing playboy tiger, Mr. Jack. This charismatic character first graced the comic strip pages on May 17, 1903. Shortly after that, the strip’s title officially changed to “Mr. Jack” on August 30, 1903, and this name remained consistent from the October 4, 1903 strip onward.

A Groundbreaking Character

What set Mr. Jack apart from previous animal characters in the world of art and fiction was his unique portrayal. While earlier animal characters often possessed human-like qualities, such as clothing and speech, Swinnerton took it further with Mr. Jack. He bestowed upon Mr. Jack an essentially human body beneath his tiger head, complete with hands rather than paws and an upright stance. This innovative approach to character design set Mr. Jack apart as perhaps the “first fully-realized funny animal” character. This groundbreaking development laid the foundation for a well-established character type that would later flourish in comics and other media.

Controversy and Evolution

Despite Mr. Jack’s popularity, his rakish behavior led to protests, with concerns that he set a bad example for children. As a result, the comic strip was relocated to the newspaper’s sports section after 1904, as it was deemed more suitable for an adult and predominantly male audience. Furthermore, Mr. Jack’s appearances in the strip became less frequent as Swinnerton shifted his focus to his new creation, “Little Jimmy,” which gained more widespread popularity.

After a brief hiatus, Mr. Jack returned to the Sunday pages in January 1905, only occasionally appearing until January 21, 1906. The character was revived as a weekday strip on October 3, 1907, with sporadic runs during specific periods, particularly in 1912 and 1915. There was a temporary alteration to the strip’s title from March to September 1916, when it was referred to as “The Escapades of Mr. Jack.” According to some sources, It reverted to the original “Mr. Jack” title, and the strip continued until at least 1919.

Despite this endpoint, there is some debate among historians about the exact timeline of Mr. Jack’s adventures, as specific strips depicted him surreptitiously drinking alcohol behind the backs of police officers. These strips appear to be associated with the Prohibition era of the 1920s, suggesting that Mr. Jack’s legacy may have extended beyond the documented years.

The Final Days

On January 24, 1926, a new chapter began for Mr. Jack as his strip transformed into a topper above the “Little Jimmy” Sunday page. This change also brought about a notable shift in the character’s portrayal, with a more toned-down approach. Nevertheless, this incarnation of Mr. Jack continued until 1935, when it was discontinued, making way for a new comic strip, “Li’l Ole Orvie.”

Despite the conclusion of his comic strip, Swinnerton continued to draw “Little Jimmy” until 1958, cementing his place in the world of comics. Tragically, Jimmy Swinnerton passed away in 1974, but the legacy of Mr. Jack and the contributions of his creator lived on.

Characters and Stories

Mr. Jack: The Pioneering Playboy Tiger Who Shaped Comic Strip History

At the heart of Mr. Jack’s comic strip was the charismatic titular character, a married yet philandering tiger with a penchant for flirting with any lady who crossed his path. This playful and often shameless behavior earned him the ire of his long-suffering spouse, affectionately called “Wifey.” In many episodes, “Wifey” was left with the unenviable task of seeking forgiveness for her husband’s misbehavior, only to ultimately take matters into her paws, so to speak, and deliver a well-deserved punishment. Despite the humorous consequences of Mr. Jack’s actions, he often concluded that his adventures were well worth the trouble.

In the universe of Mr. Jack, this charismatic tiger was often seen as the life of the party, charming to women and admired by men. While his antics sometimes led to trouble, his enduring popularity among less conservative characters in his world showcased the lasting appeal of his character.


Although Mr. Jack never attained the same level of popularity as “Little Jimmy,” his influence on the comic strip genre is undeniable. One clear derivative of Mr. Jack’s character was “Mr. George,” created by Harold Knerr, who also took the helm of “The Katzenjammer Kids.” This spin-off character, “Mr. George,” further underscores the enduring impact of Mr. Jack in the world of comic strips.
