Technology and Change 1

The Civil War significantly impacted the country's history, highlighting changes that had started in the previous 20 to 30 years. The war boosted manufacturing, leading to a rise in technology and innovation. Before 1860, 36,000 patents were granted, which soared to 440,000 in the next 30 years, reaching nearly a million in the early 20th century. Key inventions like the telegraph, telephone, typewriter, and Edison’s light bulb transformed communication and productivity. The iron and steel industry also thrived, with new ore deposits discovered, particularly in the Mesabi range, allowing for cheaper and higher quality steel production.
