In order to popularize these crops, he developed over 300 by-products, including cereals, oils, dyes, soaps, and new foods. At the same time, he conducted his remarkable school on wheels, a traveling classroom from which he taught Alabama farmers the basics of soil enrichment. When he died on June 5, 1943, he was one of America's most honored scientists, having brought prosperity to large areas of the impoverished South. 9 Which of the following is an accurate statement about Carver's childhood?
