Bloomberg by Bloomberg is an autobiographical book written by Michael Bloomberg, published in 1997. It chronicles his personal and professional journey, from his upbringing in a middle-class family in Boston, his education at Johns Hopkins University and Harvard Business School, his early career on Wall Street at Salomon Brothers where he rose to partner, his abrupt dismissal in 1981, and his subsequent founding of Innovative Market Systems (later Bloomberg L.P.) with a $10 million severance package. The book details the creation of the Bloomberg Terminal, a revolutionary financial data and analytics tool, and offers insights into Bloomberg's entrepreneurial philosophy, management style, risk-taking approach, and views on business, politics, and life. It serves as a key source for understanding the origins of Bloomberg L.P., one of the world's largest financial information providers, and Bloomberg's mindset that later influenced his mayoral tenure in New York City and his political ambitions.
