Mark Zuckerberg is an American technology entrepreneur and philanthropist, best known as the co-founder and CEO of Facebook, the world's largest social networking platform. He was born in 1984 in White Plains, New York, and grew up in the nearby town of Dobbs Ferry. Zuckerberg showed an early interest in computers, and by the age of 12, he had already created a program called Synapse, which was designed to learn the user's music preferences and create custom playlists.

In 2002, Zuckerberg enrolled at Harvard University, where he studied computer science. While at Harvard, he developed a program called Facemash, which allowed students to compare the attractiveness of their classmates. The program was quickly shut down by the university, but it served as the inspiration for Zuckerberg's next project: Thefacebook.com, which was launched in 2004 and eventually became Facebook.

Facebook quickly gained popularity, and within a year, it expanded to other universities and eventually to the general public. In 2012, Facebook went public and became the largest social networking platform in the world.

Zuckerberg has faced controversy over issues such as user privacy and the spread of misinformation on the platform. Despite this, he has remained as CEO of Facebook, and as of 2021, he is one of the youngest billionaires in the world. He is also known for his philanthropy, particularly in the areas of education and healthcare.

Zuckerberg is also known for his interest in renewable energy and started the "Breakthrough Energy" initiative with other entrepreneurs to accelerate the development of clean energy solutions.
