[4] In 1871, at 21 years old, Frick joined two cousins and a friend in a small partnership, using a beehive oven to turn coal into coke for use in steel manufacturing, and vowed to be a millionaire by the age of thirty.

[7] At the suggestion of his friend Benjamin Ruff, Frick helped to found the exclusive South Fork Fishing and Hunting Club high above Johnstown, Pennsylvania.

[9] Poor repairs and maintenance, unusually high snow melt and heavy spring rains combined to cause the dam to give way on May 31, 1889, resulting in the Johnstown Flood.

The American Society of Civil Engineers launched an investigation of the South Fork Dam breach immediately after the flood.

[15] In 1907, as prohibition became more popular across the country, Frick and Mellon removed their names from the distilling license, although they retained ownership in the company.

Frick was known for his anti-union policy and as negotiations were still taking place, he ordered the construction of a solid board fence topped with barbed wire around mill property.

With the mill ringed by striking workers, Pinkerton agents planned to access the plant grounds from the river.

Three hundred Pinkerton detectives[5] assembled on the Davis Island Dam on the Ohio River about five miles (8 km) below Pittsburgh at 10:30 p.m. on the night of July 5, 1892.

They were given Winchester rifles, placed on two specially-equipped barges and towed upriver with the object of removing the workers by force.

[5][16] The Pinkerton agents were thrown back, and the riot was ultimately quelled only by the intervention of 8,000 armed state militia under the command of Major General George R.

Because of this strike, people like Alan Petrucelli had thought that he is depicted as the "rich man" in Maxo Vanka's murals in St. Nicholas Croatian Church, but the Society to Preserve the Millvale Murals of Maxo Vanka (which works to preserve the artwork) says it depicts Andrew Mellon.

On July 23, Berkman, armed with a revolver and a sharpened steel file, entered Frick's office in downtown Pittsburgh.

[5] Frick, realizing what was happening, attempted to rise from his chair while Berkman pulled a revolver and fired at nearly point-blank range.

The bullet hit Frick in the left earlobe, penetrated his neck near the base of the skull, and lodged in his back.

[18] All three men crashed to the floor, where Berkman managed to stab Frick four times in the leg with the pointed steel file before finally being subdued by other employees and a carpenter, who had rushed into the office.

In 1882, after the formation of the partnership with Andrew Carnegie, Frick and his wife bought a home they eventually called Clayton, an estate in Pittsburgh's East End.

[20] In 1904, he built Eagle Rock, a summer estate at Prides Crossing in Beverly, Massachusetts on Boston's fashionable North Shore.

Frick had engaged a similar stratagem when orchestrating the ouster of the man who had saved his life, John George Alexander Leishman, from the presidency of Carnegie Steel a decade beforehand.

It contains many works of art dating from the pre-Renaissance up to the post-Impressionist eras, displayed at the Henry Clay Frick House (built in 1913) in no logical or chronological order.

Frick frequently used the car for travel between his residences in New York City, Pittsburgh, and Prides Crossing, Massachusetts, as well for trips to places such as Palm Beach, Florida, and Aiken, South Carolina.

Photographs of family and friends travelling on the Westmoreland form part of the Frick archive, as do the original construction plans and upholstery fabric samples.

[23][24] Frick and his wife Adelaide had booked tickets to travel back to New York on the inaugural trip of the RMS Titanic in 1912, along with J.P. Morgan.

Documentation includes first business activities, first coal firm, H.C. Frick & Company, to the formation of United States Steel Corporation on March 2, 1901.
