Oh Henry!

Oh Henry! is a chocolate candy bar featuring a core of chewy fudge layered with caramel and crunchy peanuts, all enrobed in a milk chocolate coating. Introduced in 1920 by the Williamson Candy Company in Chicago, Illinois, the bar was one of the first major American confections combining chocolate, peanuts, and caramel, quickly gaining popularity with production reaching 5 million bars per month by 1922. The origin of its name remains uncertain, with legends suggesting it derived from a flirtatious young man named Henry who frequented the company's factory and prompted exclamations of "Oh, Henry!" from female employees, or possibly from a waiter at Williamson's favorite restaurant. The Williamson Candy Company, founded in 1917 by George H. Williamson, initially produced the bar at a facility on North Ashland Avenue before relocating to a larger plant on West Armitage Avenue in 1924. The brand underwent several ownership changes, including a merger with General Candy Company in 1926, acquisition by Warner-Lambert in 1965, and purchase by in 1984, before sold its U.S. confectionery portfolio, including Oh Henry!, to Ferrero Group in 2018. Production in the United States peaked in the mid-20th century but declined over subsequent decades, leading to discontinuation of the U.S. version in 2019 shortly before its centennial. A variant continues to be manufactured and sold in by , featuring a different recipe, including variations in and structure.

Historical Development

Invention and Early Years

The Oh Henry! candy bar was introduced in 1920 by the Williamson Candy Company of Chicago, Illinois, founded three years earlier by confectioner George H. Williamson. The bar consisted of a fudge nougat center coated in caramel and peanuts, then enrobed in milk chocolate, making it a standout in the post-World War I candy boom that saw widespread demand for affordable, portable treats. This era marked a surge in the U.S. confectionery industry, with thousands of regional producers capitalizing on soldiers' familiarity with chocolate rations to fuel a national obsession with candy bars. Initially produced in Williamson's facilities on Chicago's North Ashland Avenue, the Oh Henry! bar began with regional distribution across the Midwest, sold in local stores and theaters as a premium 10-cent treat. Lacking a formal patent, the recipe relied on Williamson's proprietary caramel-peanut formulation, which quickly differentiated it from competitors like the emerging Baby Ruth bar from rival Curtiss Candy Company. By 1921, the bar achieved early national reach, with production scaling rapidly to meet demand. In 1924, the company relocated to a larger plant on West Armitage Avenue. The company's workforce grew to over 500 employees during the 1930s. The bar's initial popularity was propelled by innovative tactics, including free samples and novelty promotions, leading to monthly production of 5 million units by 1922. Positioned as "Public Energy Number One," it appealed to a broad audience, from everyday consumers to high-society events and holiday gifting.

Ownership Changes and Discontinuations

In , Williamson Candy Company merged with General Candy Company, with George H. Williamson serving as president of the new entity. In 1965, the Williamson Candy Company was acquired by Warner-Lambert, a pharmaceutical and consumer goods , marking the first major corporate shift for the brand. Shortly thereafter, Warner-Lambert divested the Oh Henry! rights to Terson, Inc., a food packaging and confectionery firm, allowing the bar to continue production under new management focused on efficiency and distribution. By 1984, acquired the U.S. rights to Oh Henry! from Terson, integrating it into its broader portfolio and enabling wider domestic availability through 's established supply networks. In 1987, Canada acquired the rights to produce and distribute Oh Henry! in through its purchase of Nabisco's Canadian assets. Under 's ownership, the bar saw sustained production in the United States for over three decades, though it remained primarily a North American product with limited international presence. In January 2018, sold its U.S. business, including Oh Henry!, to , a of the firm Ferrero Group, as part of a $2.8 billion deal to refocus on other global priorities. , known for brands like and , assumed full control of U.S. production and marketing for the bar. Following the acquisition, discontinued Oh Henry! production in the United States in 2019, citing low sales volumes and shifting consumer preferences as key factors, which led to its temporary removal from American shelves after nearly a century of availability. This halt affected only the U.S. market, as rights in other regions operated independently. In response to fan demand and nostalgic interest, relaunched Oh Henry! by late 2022, utilizing an optimized to restore distribution through major retailers like and online platforms. As of November 2025, the bar continues to be produced in ongoing batches by , maintaining its classic composition of fudge, peanuts, caramel, and coating.

Regional Variations

United States Version

The version of the Oh Henry! bar, produced by following their parent company 's 2018 acquisition of the brand from , featured a distinctive dual-bar design consisting of two connected pieces. Each piece incorporated layers of creamy and crunchy , with a element integrated into one section for added texture contrast, all enveloped in a coating. This format differed from earlier single-bar iterations and emphasized a shareable structure reminiscent of other dual-piece confections. The bar was discontinued in 2019. Although Ferrara announced plans to relaunch it in 2022, production has not resumed as of November 2025, and the version is no longer manufactured domestically. The formulation lacked a center, prioritizing the classic combination of , , and for a chewy, nutty profile. Any availability of Oh Henry! bars is limited to imports of the Canadian version sold through online platforms like or specialty retailers.

Canadian Version

The Canadian version of the Oh Henry! bar is a single confection consisting of a central core enveloped by a layer of , surrounded by crunchy , and coated in a chocolatey shell. This format distinguishes it from variations in other markets, emphasizing a balanced combination of chewy, creamy, and crisp textures. Produced exclusively by for the Canadian market, the bar maintains the classic recipe adapted for local preferences since Hershey acquired the rights in 1987. Historically, the bar was manufactured at Hershey's , facility, which operated from 1963 until its closure in 2008 as part of a global restructuring. Following the shutdown, production shifted to other Hershey facilities, ensuring continued domestic without interruption. Unlike the U.S. version, which was discontinued in 2019 under ownership, the Canadian Oh Henry! has remained in steady production through 2025, reflecting Hershey's ongoing commitment to the brand in the region. Hershey's retention of rights in , separate from U.S. licensing changes, has supported this continuity. Each 58-gram bar provides 290 calories and 5 grams of protein, primarily from the dense coating that contributes to its satisfying crunch. The nutritional profile aligns with standard offerings, featuring sugar, , modified oils, , and unsweetened as key ingredients. Widely available at major Canadian retailers such as and , the bar is a staple in grocery aisles nationwide. It is also exported on a limited basis to the , often through specialty importers catering to border regions.

Marketing and Cultural Impact

Advertising Campaigns

The Oh Henry! candy bar's advertising efforts began in the 1920s with innovative guerrilla tactics employed by company employee John Glossinger, who plastered "Oh Henry!" stickers on walls and buildings across to generate buzz without initial corporate funding, ultimately boosting national awareness. This low-cost approach was complemented by the Williamson Candy Company's bold decision to hire the Fred M. Randall advertising agency for a pioneering national print campaign, positioning the bar as a premium 10-cent treat equivalent to homemade . Early radio promotions emerged around , sponsoring programs like the Oh Henry! Twins on station WENR to reach broader audiences through serialized . Sales of Oh Henry! remained stable during despite production challenges from material and labor shortages. Post-war efforts shifted toward mass-market appeal, with slogans like "Everybody's Candy Bar" promoting affordability at 5 cents. In the , following Nestlé's acquisition of U.S. rights in 1984, television campaigns featured comedian in a series of humorous spots that spotlighted the bar's signature "big chunk of f-u-d-g-e," airing on network TV to appeal to younger viewers with exaggerated comedy. These ads evolved the brand's messaging from exclamatory print calls in the to playful product-focused jingles, reinforcing the caramel-fudge-peanut combination.

Name Origin and Legacy

The name "Oh Henry!" originated from a young man named Henry who frequently visited the Williamson Candy Company's shop in Chicago around 1919, where female employees would call out "Oh, Henry!" when asking him to perform small tasks or favors for them. This anecdote, popularized in a 1935 Life magazine article and corroborated by Nestlé's historical accounts, inspired company founder George Williamson to name his new candy bar after the exclamation upon its introduction in 1920. Alternative theories suggest the name drew from contemporary cultural references, such as the 1920 Broadway play Oh Henry! or the pen name of short-story writer (William Sydney Porter), though these lack direct confirmation from the company. Another unverified claim posits that the bar evolved from a "Tom Henry Bar" invented by Thomas Henry of the Peerless Candy Company in the late 1910s and acquired by Williamson, who rebranded it. Early sales of the bar were notably strong in , contributing to its rapid national expansion as a popular combination . The candy bar's name has left a lasting cultural footprint, most notably appearing in the 1996 Seinfeld episode "The Caddy," where character Sue Ellen Mischke is depicted as the heiress to the Oh Henry! fortune, highlighting the brand's recognizable status in American pop culture. Its nostalgic appeal persists through collector enthusiasm for vintage wrappers from the Williamson era, which evoke mid-20th-century confectionery history. In 2022, Ferrara Candy Company announced a relaunch of the bar in the United States after its 2019 discontinuation, capitalizing on its retro charm to reengage fans, though U.S. availability has been limited as of 2025. The "Oh Henry!" was filed by the Williamson Candy Company on July 6, 1921, and registered on February 28, 1922, under U.S. Registration No. 0152550 for products. It has been renewed multiple times, with the most recent extension in 2012 maintaining active status under (a Ferrero company) for the U.S. version, while holds rights for the Canadian variant through ongoing renewals.
