On LaSalle street, the splendid brown stone front of the “Bryan Block,” at the corner of Monroe, attracts many admirers of architecture, and shows how rapidly business is progressing southward on that street.

A post-fire Bryon Block was rebuilt on the site. Both building and site were later acquired for $850,000 by Byron Laflin Smith for The Northern Trust Company, which went on the company’s books June 9, 1904. In September 1906, a massive, new pink granite structure designed by Frost and Granger architects opened on the site as the Company’s new headquarters which stands as its world headquarters to this day.
