Abraham Block was the patriarch of the first documented Jewish family to immigrate to the state of Arkansas. After a period as a businessman in Virginia, Block moved his family to southwest Arkansas in search of new economic opportunities. Along with his sons, he created a regional merchant empire with businesses in Washington (Hempstead County), Fulton (Hempstead County), and Paraclifta (Sevier County) in Arkansas, as well as in New Orleans, Louisiana, and at several stops along the railroad in Texas from Houston to Dallas. The family home in Washington has been restored and is currently a house museum in Historic Washington State Park.

The significance of the Block family on the growth of Arkansas Judaism cannot be understated. The Blocks established a “chain store” business that set the precedent for future generations of Jewish businessmen in the state.
