950 Sedgwick Avenue, ca. 1934.

The 8-story building with the lighthouse is the home of the H.W. Wilson Company, a publishing firm that has been in business for over a century. Halsey William Wilson, who originally founded the company in Minneapolis, produced an old book that explained how he had the lighthouse built in 1929, after moving the business to New York. He wrote that the lighthouse was meant to symbolize the company's mission:

“To give guidance to those seeking their way through the maze of books and periodicals, without which they would be lost.”

In 1998, the lighthouse was relit after being out of commission for many years to celebrate the company's centennial.
