Johan Bryntesson was born in the parish of Ärtemark in the traditional province of Dalsland, Sweden. He came to the United States at the age of 16 and headed to the upper Peninsula of Michigan where he worked in copper and iron mines for about ten years and became a United States citizen. Citizenship was granted in Michigan in 1896.
In 1898, Brynteson arrived at Unalakleet, Alaska on the eastern coast of Norton Sound, Bering Sea to find coal for the Swedish Mission Covenant. A gold-seeking venture which commenced in mid-September 1898 with Erik O. Lindblom and Jafet Lindeberg proved quite successful. Brynteson and partners soon knew they had a major discovery. In 1898, the three formed the Pioneer Mining and Ditch Company. The company was the largest mining company operating in Nome, Alaska, in the years following the discovery of gold.
Brynteson was the first of the party to leave Alaska and the only one to return to his homeland. Brynteson used his fortune to fund other business ventures and for philanthropy. Brynteson purchased a farm in Santa Clara County, California later known as The Pruneyard. He established a home for sailors in San Francisco and endowed charitable works in Chicago. He also financed the construction of the Ice Palace in Stockholm for the 1912 Olympic Games.
