Alonzo "Lon" Franklin Herndon was an African-American entrepreneur and businessman in Atlanta, Georgia. Born into slavery, he became one of the first African American millionaires in the United States, first achieving success by owning and operating three large barber shops in the city that served prominent white men. In 1905 he became the founder and president of what he built to be one of the United States' most well-known and successful African-American businesses, the Atlanta Family Life Insurance Company.

In the US, Black-owned businesses, also known as African American businesses, originated in the days of slavery before 1865. Emancipation and civil rights permitted businessmen to operate inside the American legal structure starting in the Reconstruction Era (1863–77) and afterwards. By the 1890s, thousands of small business operations had opened in urban areas. The most rapid growth came in the early 20th century, as the increasingly rigid Jim Crow system of segregation moved urban Blacks into a community large enough to support a business establishment. The National Negro Business League—which Booker T. Washington, college president, promoted—opened over 600 chapters. It reached every city with a significant Black population.
