Wattis was born in Uinta, Utah Territory, the fourth of seven children born to Edmund Orson Wattis and Mary Jane Corey. With his brother E.O., he formed a firm to lay track for the expanding railroads. The fledgling Wattis Brothers firm was wiped out in the panic of 1893. While William continued to try to find construction projects, Edmund focused his energies on running a sheep ranch the brothers had established in the Weber Valley. This ranch and others would later provide the financial strength for the large construction projects to come. Wattis married his sweetheart, Anna Maria Dorothea Sophie Stander, on January 9, 1889. They had three daughters and one son. In 1897, they lost Florence Louise, age 5, and Edmund, age 1, within six months of each other while living in Astoria, Oregon.
Utah Construction Company
In 1900, the Wattis Brothers again attempted to be partners in contracting. They founded the Utah Construction Company along with David Eccles and Thomas D. Dee. A short four years after its founding, Utah Construction Company was awarded the contract to build the Feather River route between Oakland and Salt Lake City. This $60 million contract was challenging, but after five years, very profitable. The Feather River route was complete for the Western Pacific Railroad in 1911. The Utah Construction Company also was a building contractor for the Utah State Capital. In 1912, after the death of David Eccles, W. H. was elected President of The Utah Construction Company. The company thrived, and soon captured a large share of the tunneling, grading, and track projects in the rapidly expanding railroads in the mountain west. Seeing the end of railroad expansion, the Wattis Brothers looked for ways to diversify their construction risks.
In 1915, the Wattis brothers bought the Wattis Coal Company and the Wattis mine shipped its first coal on April 11, 1918. The ghost town of Wattis, Utah, located south of Price, is named after the Wattis brothers. In 1919 the company merged with the Lion Coal Company, owned by the Eccles family.
Ogden Union Stockyard Company
On July 29, 1916, W.H. formed a partnership in incorporating the Ogden Union Stockyard Company, formerly known as the Ogden Packing and Provision Company, which proved to be quite profitable—by 1934 the company made over $2 million.
Building dams
In 1917, Utah Construction Company was awarded the $7 million O'Shaughnessy Dam contract, a controversial project that impounds the Tuolumne River in the Hetch Hetchy Valley of California's Sierra Nevada mountains. Success with the O'Shaughnessy Dam convinced the Wattis Brothers to bid on more dam projects. In 1922, Utah Construction Company formed a partnership with the Morrison-Knudsen Company of Boise, Idaho. With Frank Crowe as the chief engineer, the MK UC partnership successfully built dams throughout the American west.
W.H. was also a prominent businessman in Ogden, Utah and known throughout Utah. He was director of The National Bank, director of the Utah-Idaho Central Railroad, and president of Dee Memorial Hospital from 1917 to 1929. As president he oversaw the new L-shaped addition equipped with elevators, making Dee one of the most modern and up-to-date hospitals of its time at an estimated cost of $160,000. In January 1921, Wattis was elected general manager and president of Utah-Idaho Sugar Company and vice president and general manager of the Canadian Sugar Company Ltd., the Canadian branch of Utah-Idaho Sugar Company. Due to political and legal troubles with the Utah-Idaho Sugar Company, Wattis was indicted on price fixing charges and was found in contempt of court by Judge Tilman D. Johnson, which caused him to withdraw from a 1920 run for governor. He was elected Captain of the Alta Club, one of the oldest gentlemen's clubs in Utah, on April 22, 1921. On September 27, 1927, Wattis was nominated and elected Vice President of the Associated General Contractors of America, and later nominated on October 20, 1927 to be the vice president over the states of Utah, Nevada, California and Arizona. In 1929, the Wattis Brothers spearheaded the formation of Six Companies to build the Hoover Dam, which was the largest construction project ever tackled by the US Government up to that time. W.H. was elected as the Six Companies' first President.
Death
On March 23, 1931, Time Magazine wrote: However, he did not live to see Hoover Dam completed; W.H. Wattis died in California, on September 13, 1931 of cancer. Shortly before his death on June 9, 1931, the University of Utah honored him with a Doctorate of Law degree. Wattis loved life, family and friends. He was an avid golfer, hunter and traveler.
