No, Thomas Edison did not develop the first steam engine in the United States. The steam engine was invented earlier by figures like Thomas Newcomen and James Watt in the 18th century. Edison is best known for his contributions to electric power and invention of devices like the phonograph and the electric light bulb, rather than steam engine technology.
