Thomas William Lawson (February 26, 1857 - February 8, 1925) was an American businessman and author, known for his involvement in the stock market and his speculative investments. He was a controversial figure in his time, often associated with the manipulation of stocks, a practice that made him famous as well as infamous. His efforts did, however, contribute to legislation aimed at regulating the financial markets. As an author, Lawson is best remembered for his novel 'Friday, the Thirteenth,' which delineated the dark and psychological aspects of the financial world. Published in 1907, the book weaved a narrative around the superstitions of the titular date and the Wall Street market chaos it could influence. This work is an early example of literature that delves into the complexities of the American financial systems and the psychological impact on those involved in it, blending Lawson's intimate knowledge of stock trading with fictional storytelling. His literary style in this novel can be best described as a form of muckraking, aiming to expose the excesses and moral compromises of the financial industry. Though not primarily remembered as an author, Lawson's 'Friday, the Thirteenth' stands as a significant contribution to early 20th-century American literature, offering insight into the financial mindsets and practices of the time.
