Reymer and Anderson was one of the first confectionaries in Pittsburgh and it boomed during the Civil War when people sent their candies to soldiers. They prospered during the last half of the nineteenth century as Phillip Reymer's sons, Jacob and Harmer, took over the business. By 1906 when the new factory was built, the Reymer family had left the business but their name lived on. In 1908 the firm claimed that it was "one of the largest confectionary houses in the world," and that it had 5,000 vendors in the Pittsburgh area.
The firm ran five teahouses in Pittsburgh. These may have contributed to perception that the firm made quality products, but were unprofitable. An uncarbonated soft drink "Lemon Blennd" accounted for 70% of their sales in 1959. The company was taken over in 1959 by a competitor, Dimling's, which went out of business in 1969.
