It was a thriving wholesale merchant partnership which included a grocery and dry goods store across from the Governor's Palace[1][2] It was the first Jewish mercantile company in Santa Fe. The Spiegelberg brothers expanded to include four other brothers. They served as sutlers to the American military and as Indian traders. They later established and were major stockholders in the Second National Bank of Santa Fe.[3] The reach of their numerous investments and the bank have been described as a regional business empire, spreading across large parts of the Southwest.[4] Investments included mining operations, insurance, and real estate ventures.
