Harbert, who was a co-founder of Harbert Corp. and who headed up the company's international operations. In 1993 Harbert Corp. sold its international construction division to Bill. Today the company's former international construction division is known as B.L. Harbert International and is run by Bill's son Billy. Life Harbert served as a private in the U.S. Army in Europe during World War II. He received a degree in civil engineering from Auburn University in 1946. In 1949, he founded the Harbert Corporation. The company main business was its domestic and international construction unit, which at the time was one of the largest in the country.

Harbert, which today is known as B.L. Harbert International. Other company subsidiaries engaged in mining, pipeline development, land development, limestone quarrying, road construction.
