Review Questions

• How did Thomas Edison's inventions reflect the broader themes of industrialization during his time?
  • Edison's inventions, particularly the light bulb and phonograph, showcased the spirit of industrialization by improving everyday life and creating new industries. His work facilitated urban development through better lighting and transformed entertainment with recorded music. These innovations not only demonstrated technological progress but also fueled economic growth and changed societal structures during the Gilded Age.
• Evaluate the significance of Edison's research laboratory in Menlo Park for future inventors and industries.
  • Edison's research laboratory in Menlo Park was significant because it pioneered the concept of organized industrial research and collaborative invention. This approach allowed for systematic experimentation and rapid prototyping, which set a precedent for future innovation centers. The lab became a blueprint for how inventors could work together to solve complex problems, ultimately leading to advances across multiple industries.
• Analyze how Edison's rivalry with Tesla influenced the development of electrical systems in America.
  • Edison's rivalry with Nikola Tesla over AC versus DC power systems significantly influenced the electrical infrastructure in America. Edison's support for direct current (DC) faced strong competition from Tesla's alternating current (AC), which proved to be more efficient for long-distance power transmission. This conflict culminated in what is known as the 'War of Currents,' ultimately leading to the widespread adoption of AC as the standard for electrical power distribution, shaping the modern electric grid we rely on today.
