There are several examples of scientists who had brilliant ideas and went on to become millionaires. Here are a few notable examples:

1. Thomas Edison: Thomas Edison was an American inventor and businessman who held over 1,000 patents. His most famous invention is the practical electric light bulb. Edison's brilliant ideas and entrepreneurial skills helped him found the Edison General Electric Company (now known as General Electric), which made him a millionaire.

2. Nikola Tesla: Nikola Tesla was a Serbian-American inventor, electrical engineer, and physicist. He made significant contributions to the development of alternating current (AC) electrical systems. Although Tesla did not become a millionaire during his lifetime, his ideas and inventions laid the foundation for modern power generation and transmission, making many others wealthy.

3. James Dyson: James Dyson is a British inventor and industrial designer. He is best known for inventing the Dual Cyclone bagless vacuum cleaner, which revolutionized the vacuum industry. Dyson's brilliant idea and determination led him to establish the Dyson company, which has since expanded to produce a wide range of innovative household appliances. As of 2021, James Dyson has a net worth of over $20 billion.

4. Elizabeth Holmes: Elizabeth Holmes, although her case is controversial and subject to legal proceedings, is an example of a scientist who became a billionaire through her biotech startup, Theranos. Holmes claimed to have developed a revolutionary blood testing technology that could detect a wide range of diseases from a small amount of blood. However, the technology was later revealed to be fraudulent. Nevertheless, Holmes' initial success and wealth were based on her brilliant idea and ability to convince investors.

It's important to note that not all scientists with brilliant ideas become millionaires. Many scientists may make significant contributions to their fields but may not necessarily commercialize their inventions or ideas. Additionally, financial success often depends on various factors such as entrepreneurship, market demand, and effective business strategies.
