In 1838 Allen Comstock opened a stove & hardware shop in Quincy, IL—laying the groundwork for America’s oldest stove company.
Partnering soon after, Castle transformed the business into a grey-iron foundry—meeting the frontier’s need for durable cooking & heating stoves.
Early in the nineteenth century, Illinois sat on the nation’s western fringe. Settlers heading to west-central Illinois traveled light and purchased heavy essentials—like cast-iron cookware and heating stoves—after they arrived.
Quincy’s deep natural harbor on the Mississippi made it a supply hub. Hardware stores were among the first businesses to open, selling riverboat-shipped goods from New York and St. Louis and laying the groundwork for a regional stove industry.
Moving beyond retail, A. Comstock & Company launched a grey-iron foundry in Quincy to build its own products. The operation became known as the Phoenix Stove Works, producing stoves and hollow-ware close to where customers needed them.
The foundry ignited a manufacturing cluster: Quincy soon hosted numerous stove works—many founded by former Comstock-Castle employees—as the city emerged as a Midwestern center for stove production.
The firm incorporated in 1884 (later re-incorporating as a perpetual corporation). During the Civil War era, the company name became Comstock-Castle Stove Company, with the Castle family assuming leadership.
By the early 1900s Quincy made more stoves than anywhere else in the U.S., and Comstock-Castle proudly billed itself the “World’s Largest Sellers”—a claim rooted in decades of continuous, locally built production.
