Monarch Engineering Co.

Monarch Engineering Co. was an American firm of Denver, Colorado, active in engineering and construction services. John A. Crook and his brother, Guy A. Crook of Falls City, were founders of the Monarch Engineering company which had its origin and main offices at Falls City, with offices in Kansas City, and Denver. Under the management of these men the Monarch Engineering company had risen to become an important and prosperous concern and a vast amount of bridge construction, city paving, irrigation-dam building, and public building work has been done under their supervision. Within ten years after the firm had been in operation, or since 1908, its activities constantly increased and in 1917 they purchased the Denver Steel and Iron Works in order to facilitate the material supply part of the construction work in which they were engaged.

Mr. Crook was born in Falls City, April 9, 1879, a son of the late W. H. Crook, hardware merchant. He received his education in the public and high schools of Falls City and studied in the state university. He pursued an engineering course with the International Correspondence school of Scranton, Pa., and was first employed with the Canton Bridge company of Omaha as structural and construction engineer for two years, 1898 to 1900. He returned to Falls City in 1900 and entered the employ of the John Gilligan Bridge company and remained with this concern until 1908. He then established the Monarch Engineering Company, being joined by his brother, Guy A. Crook, in 1910.

In October 1916 the growth of the concern required that he locate in Denver where he had charge of the Denver Steel and Iron Works and looked after the company's western operations.
