Few sites are etched into Petaluma history deeper than the Petaluma Incubator Company, the engine behind the city’s reign as the World’s Egg Basket. Yet, thanks to urban renewal efforts in the 1960s, nothing remains of the building today other than a rock wall lining Brewster’s Beer Garden.

The incubator company had its genesis in 1877, when Isaac Dias, a young Jewish dentist from New Orleans invented an incubator capable of maintaining a steady temperature of 103 degrees, the same as a brooding hen’s body. By accelerating the hatching of newly laid eggs, the incubator freed the hen from her maternal nesting duties, allowing her to lay more.[1]

Dias patented his invention, and was joined in marketing it in 1882 by one of his patients, Lyman Byce, a 26-year-old medical student from Canada, who came to visit a sister in Petaluma, seeking the health benefits of the area’s Mediterranean sea breezes.[2]

That same mild climate, along with the valley’s rich, alluvial soil, would set the stage for the chicken mania that followed.

In 1881, Byce—the Steve Jobs to Dias’ Steve Wozniak— joined Dias in forming the Petaluma Incubator Company, soon setting up their factory in a former armory near the Washington Street Bridge.[3]

After Dias’s mysterious death in an 1884 duck hunting accident, Byce employed his marketing talents in taking the Petaluma Incubator Company to new heights. Positioning himself as the “father of chickendome,” he wrote Dias out of the story.[4]

In 1889, Byce moved the incubator factory to the Hopper Building at 230-236 Main Street, beside George P. McNear’s Oriental Mills & Feed Store. After a fire burned down McNear’s building in 1902, Byce purchased the lot at 238-242 Main, and constructed a modern new factory in its place.[5]

Overexpansion and distressed sales during World War I forced Byce to declare bankruptcy in 1919, and move to a smaller factory on East Washington Street. His former building was converted into a poultry packing plant by the Petaluma Poultry Company.[6]

In 1938, the poultry company sold the building to Petaluma Milling Company, a feed and mill store. It operated until 1967, when the city, championing urban renewal, condemned both buildings that had once housed the Petaluma Incubator Company, 230-236 and 238-242, giving the owners the choice of either rehabilitating them or tearing them down. They buildings were demolished in 1968.[7]

The lots remained vacant until 2016, when Brewster’s Beer Garden created an open air facility on their ground floor facing Water Street, leaving a hole in the street landscape of Petaluma Boulevard North, a reminder of good intentions gone bad.[8]
