"Dr. Thayer began a series of experiments in 1850, aiming to perfect the technique of evaporating in vacuum with the goal of preparing extracts in a concentrated form. With the success of these experiments, he began the manufacture of fluid extracts. During the Civil War, the products of his establishment were in active demand for the Army, as the government looked to Henry Thayer & Co for a large portion of its hospital supplies. The products found favor with all practitioners in the treatment of disease. During this period of time, Henry Thayer & Co has been described as the largest manufacturer of pharmaceuticals in America, finding sale of the company’s preparations both at home and abroad."
