The Kalamazoo Gals: The Untold Story of Women Who Built Gibson Guitars During World War II
During World War II, while American men bravely fought on the frontlines, a group of unsung heroines stepped into the spotlight. While most women took up factory jobs to support the war effort, a remarkable group found themselves in an unexpected role—crafting Gibson guitars. This hidden piece of history is finally coming to light thanks to author and guitar enthusiast John Thomas, who sought to honor the women who kept the Gibson guitar legacy alive during the war.

The Enigmatic Photo That Unveiled the Truth The journey began when John Thomas stumbled upon a black-and-white wartime photo taken at the Gibson guitar factory in Michigan. Amongst the 75 individuals in the photo, almost all were women. Intrigued, Thomas set out to find the remarkable women behind the image, and their stories began to unfold.
The Kalamazoo Gals: Women in a Man’s World Through diligent research, Thomas connected with a dozen former Gibson factory workers, now residing in Kalamazoo, Michigan. One of them, Irene Stearns, vividly recalls her time working at the factory. Stearns joined Gibson during the war years and played a crucial role in crafting guitar strings for the thousands of instruments produced at the time. She fondly remembers hearing famous musicians playing beautiful guitars on the other side of the factory wall.
A Hidden Secret: The Absence of Recognition Thomas discovered that Gibson never officially acknowledged the women who built the guitars during the war years. In fact, the company’s official history suggested that production ceased entirely during that period. Speculating on the reasons behind this secrecy, Thomas proposes that executives feared potential buyers might not embrace instruments built by women.

Unleashing the Music: A Record of Empowerment To further illuminate the story, Thomas felt compelled to create a musical recording that would resonate with the remarkable achievements of the Kalamazoo Gals. Collecting and borrowing vintage Gibson guitars from the World War II era, he enlisted the talents of professional musician Lauren Sheehan. Together, they embarked on a project to capture the essence of the guitars made by these talented women.
The Signature “Banner” Guitars and Refined Craftsmanship Sheehan and Thomas quickly recognized the distinguishing feature of the guitars made during the women’s tenure—the golden banner adorning the headstock, emblazoned with the words, “Only a Gibson is good enough.” This unique logo only appeared on World War II-era guitars, earning them the nickname “Banner” guitars. Sheehan believes this detail exemplifies the exquisite craftsmanship and attention to detail that characterized the instruments made during this period.
Unveiling the Refined Sound and Rich Heritage Through meticulous research and modern technology, Thomas validated his belief that the guitars crafted by the Kalamazoo Gals possessed a refined quality. X-ray analysis of vintage guitars showcased the women’s attention to detail, as the components were measurably thinner compared to their male predecessors and successors. The tone and quality of the instruments spoke volumes, reinforcing the exceptional craftsmanship of these pioneering women.

The incredible tale of the Kalamazoo Gals, their resilience, and their hidden contributions to the Gibson guitar legacy during World War II is finally emerging from the shadows. Their remarkable story serves as a testament to the spirit of women in a male-dominated industry and highlights the rich musical heritage they helped shape.
