Who was Andrew Carnegie

 Andrew Carnegie was a Scottish-American industrialist and philanthropist who played a key role in the development of the American steel industry in the late 19th and early 20th centuries. Born in Dunfermline, Scotland in 1835, Carnegie immigrated to the United States with his family when he was a boy. He started his career as a telegrapher and eventually worked his way up to become a railroad manager and financier.

In the 1870s, Carnegie entered the steel industry and went on to build a massive steel empire through a series of business ventures and acquisitions. At its peak, Carnegie Steel was the largest and most efficient steel producer in the world, and Carnegie himself became one of the wealthiest men in history.

In addition to his business success, Carnegie is also known for his philanthropy. He donated large sums of money to various causes, including education, science, and the arts, and is credited with helping to establish the modern system of philanthropy. Carnegie died in 1919 at the age of 84.
