On April 7, 1723 Emanuel Swedenborg was invited to take his seat on the Board of Mines. He had received his commission from King Karl XII on December 18, 1716. For seven years the gifted bishop’s son had struggled to have the board, Sweden’s most powerful economic institution, recognize the legitimacy of his extra-ordinary appointment. The decision to seat Swedenborg reflects well on both Swedenborg and the board. To understand why, it is necessary to explore the history, the structure, functions, and the personnel of the Board of Mines, as well as Swedenborg’s effort to develop competencies in areas related to the work of the board during his years in limbo.
