Royal Baking Powder Company

The Royal Baking Powder Company was one of the largest producers of baking powder in the US.

It was started by both Joseph Christoffel Hoagland and William Ziegler in 1866. In 1929, the Royal Baking Powder Co., along with four other companies including the Fleischmann's Yeast Company, merged to form Standard Brands, the number-two brand of packaged foods in America after General Foods.
