FAQ
Reader questions
How reliable are historical estimates of Andrew Mellon net worth?
Estimates are informed guesses based on available records, often differing by large margins due to valuation methods and inflation assumptions. Ranges are more informative than single figures.
What proportion of his wealth came from government service?
His public salary was modest relative to business income. Policy influence mattered more for shaping the legal environment in which his fortune grew than for direct earnings.
Did the Great Depression erase most of his wealth?
Asset values fell sharply after 1929, but diversified holdings and ongoing income streams preserved significant capital. The losses, while substantial, did not eliminate his top-tier status.
