An Enslaved Gardener Transformed the Pecan into a Cash Crop

In the 19th century, an enslaved gardener named Antoine perfected pecan tree grafting, creating the uniform 'Centennial' variety that launched the commercial pecan industry. Before this, pecan trees grown from seeds produced unpredictable nuts, making large-scale farming impossible. Antoine's propagation method—developed while enslaved—solved this, transforming a wild nut into a reliable cash crop. The pecan industry is now worth over $400 million annually, built directly on his innovation.
