The story
Throughout its history, the firm's headquarters has been located in the area of Times Square, in midtown Manhattan, where it grew from fewer than a dozen lawyers originally to nearly 800. A full-service practice, it is currently among the ten largest law firms in New York City.
William R. Rose started the firm that is now Proskauer when, at 21 years of age, he opened a law firm on Broadway in Downtown Manhattan in 1875. In 1907, Rose promoted associate Benjamin Paskus to partner and renamed the firm Rose & Paskus. Rose & Paskus was one of the first firms to develop a specialized tax practice after the passage of the Sixteenth Amendment to the United States Constitution in 1913. In 1930, Judge Joseph M. Proskauer resigned his position on New York's Appellate Division to join the firm, which was then renamed Proskauer, Rose & Paskus. The firm shortened its name to Proskauer Rose in 1997.
The firm has historically focused its practice on labor and employment law, as well as building up significant litigation, private capital, health care, sports and entertainment, bankruptcy, and taxation practices.
