There isn’t a single confirmed inventor of the Sloppy Joe, but several strong origin stories compete for the title.

Quick Scoop: Who Probably Invented Sloppy Joes?

Most food historians agree the Sloppy Joe likely evolved from “loose meat” sandwiches in the Midwest, especially Iowa, in the 1920s–30s, rather than from one clearly documented chef.

The three main contenders:

  1. The Iowa “cook named Joe” (most cited in U.S. sources)
    • In Sioux City, Iowa, cafes were selling loose meat sandwiches (ground beef on a bun, lightly seasoned, but without tomato sauce).
 * One popular theory says that **a cook named Joe** at a cafe in Sioux City added tomato sauce to his loose meat, creating the messy, saucy sandwich that got called a “Sloppy Joe.”

 * H.J. Heinz test kitchen research at the Carnegie Library also points to a **1930s Sioux City loose‑meat cook named Joe** as the likely source, which is why many writers treat this as the most credible origin.
  1. Ye Olde Tavern & Maid‑Rite (the “loose meat” path)
    • Ye Olde Tavern in Sioux City, opened by David Heglin in 1924, is often credited with popularizing loose meat sandwiches, a clear precursor to Sloppy Joes (but originally without tomato sauce).
 * Maid‑Rite, a 1926 Iowa chain founded by Floyd Angell, also sold loose meat sandwiches; one “camp” believes Sloppy Joes evolved from these, once sauce was added and the sandwich got messier and sweeter.
  1. The Cuban–Key West “Sloppy Joe” bars (the name and mystique)
    • In Havana, bar owner José “Sloppy Joe” Abeal y Otero is said to have served a ground‑beef‑and‑tomato sandwich in the late 1910s–1920s; some writers treat this as an early version of the Sloppy Joe idea.
 * Ernest Hemingway loved that Havana bar and later convinced his friend **Joe Russell** in Key West to rename his Silver Slipper bar “Sloppy Joe’s” and serve a similarly messy sandwich in the 1930s, which helped spread the _name_ and legend in the U.S.

Mini Takeaway

  • Most likely scenario:
    • The style of sandwich grew out of Iowa loose‑meat burgers in the 1920s–30s, probably refined by a Sioux City cook named Joe who added tomato sauce.
  • Name & myth:
    • The name “Sloppy Joe” and its romantic backstory were boosted by the Havana bar and the Key West Sloppy Joe’s, with help from Hemingway’s enthusiasm.
