James Joseph "J.J." Brown, was an American mining engineer, inventor, and self-made member of fashionable "society". His wife was RMS Titanic survivor Molly Brown. J.J. was born in Waymart, Pennsylvania. His father, James Brown, was an Irish immigrant. His mother, Cecilia Palmer, was a schoolteacher. J.J's family moved to Pittston, Pennsylvania shortly after his birth. J.J's mother home-schooled him and later sent him to St. John's Academy. He left home at the age of 23, lured by the riches in the West. His first stop was a farm in Nebraska. From Nebraska he moved to the placer mines in the Dakotas. He spent two years learning the mining trade before moving to Colorado where he tried his luck in Georgetown, Aspen, and Ashcroft. He spent another two years in the Aspen and Ashcroft area before moving to Alma, Fairplay, Red Cliff, and, finally, Leadville. He studied geology, ore deposits, and mining techniques to become a better miner.
