The refrigerator and microwave oven were invented by the following individuals:
Refrigerator: The modern refrigerator, as we know it today, was not invented by a single individual but rather through the collective efforts of several inventors and engineers over the years. Notable contributors to the development of the refrigerator include:
- Oliver Evans (1745-1819): Evans designed a closed vapor-compression refrigeration system in 1805, which laid the foundation for later developments.
- Jacob Perkins (1766-1849): Perkins invented the vapor-compression refrigeration system in 1834, which was an important milestone in refrigerator technology.
- Carl von Linde (1842-1934): Linde contributed to the development of efficient refrigeration technology and is considered one of the pioneers in the field.
- Albert T. Marshall (1849-1915): Marshall patented the first commercial refrigerator design in 1899, which helped popularize refrigerators for household use.
Microwave Oven: The microwave oven was developed through the collaboration of several scientists and inventors, with the following individuals making significant contributions:
- Percy Spencer (1894-1970): Spencer, an American engineer, is credited with inventing the first microwave oven while working for Raytheon Corporation in 1945. He discovered that microwaves could heat food when a candy bar in his pocket melted due to the microwave radiation emitted by a magnetron, a device used in radar systems.
- Dr. John C. Randall (1905-1984) and Dr. Harry Boot (1917-1983): These British scientists played a crucial role in developing the magnetron, the key component that generates microwaves.
- Raytheon Corporation: The company Raytheon, for which Percy Spencer worked, further developed and commercialized the microwave oven technology, introducing the first commercially available microwave oven, the "Radarange," in 1947.
It's important to note that the development of complex technologies like the refrigerator and microwave oven often involves contributions from multiple inventors and engineers over an extended period, building upon each other's work to refine and improve the technology.
