His master was Joseph Davis, a Mississippi planter and older brother of future President of the Confederate States of America Jefferson Davis. mentions that Davis’ children taught Montgomery how to read and write, and he was assigned to run the general store on the Davis Bend Plantation. Because of his excellent work, Davis put Montgomery in charge of overseeing the entirety of his purchasing and shipping operations on the plantation.

Montgomery learned to survey land, techniques for flood control and the drafting of architectural plans. Commerce flowed through the rivers connecting states, and navigation became difficult due to the differences in the depths of water. Merchandise would be delayed for days if the steamboat were to go adrift, states. To solve this problem, Montgomery created a propeller for the steamboat that would allow for better navigation through shallow water.

Davis attempted to patent the device.

On June 28, 1864, Montgomery, no longer enslaved, filed for a patent for his device and was again denied.

The sale was made based on a long-term loan in the amount of $300,000.00. states that Benjamin and Isaiah pursued their dream to use the property to establish a community of former enslaved people. However, their crops were destroyed and they were unable to pay off the loan. The property was sold back to the Davis family.
