Before electric refrigerators, “iceboxes” were made of wood and filled with ice.

Iceboxes used various materials to keep the ice frozen and the food inside cool, including cork, tin, zinc, sawdust, and seaweed. In 1835, Jacob Perkins patented a refrigerator with a liquid ammonia vapor-compression cycle.

Thomas Edison is often credited with inventing the light bulb in 1879, but other inventors played a part in its creation.
