Norwich, Vermont

No. 3,636
2010 Revenue: $81.1 million

The oldest company on this year’s list, King Arthur Flour Company started as a flour import business before introducing its own product in 1896. Run for five generations by the Sands family, the now 100 percent employee-owned company manufactures flours of all kinds, gluten-free mixes and more in a township that houses three company headquarters: “Camelot,” “Avalon,” and “Excalibur.”

In this company photograph from 1896, company owners Mark Taylor, Orin Sands, and George Wood stand beside a sign heralding their new additive-free flour.
