February 21st – This Day in Stock Market History
1947 – Polaroid demonstrates its first instant camera.
Polaroid was one of the premier tech stock of its day. The company’s founder, Edwin Land, was a prolific inventor who was viewed as the next Thomas Edison, and was a huge inspiration to Apple’s founder Steve Jobs.

Land would found the company in 1937 after studying chemistry at Harvard for a year and inventing the plastic sheet-light polarizer in 1929. Land would run Polaroid from its founding in 1937 until 1981, seeing his company grow to as many as 28,000 employees and doing $1.4 billion in sales.
However, the company was never able to adapt to the rise in digital photography, and would be bankrupt by 2001.
