In 1952, Stuart Lathan and Charles Lumsden founded Lathan Lumsden & Company with a gentlemen’s handshake, setting the stage for what would become one of the largest and most respected certified public accounting and consulting firms in Western New York.

As the demand for professional services grew, Lathan and Lumsden expanded services. Richard McCormick, who had moved to Buffalo from New York City, joined the practice in 1957, and the Firm was renamed Lathan Lumsden McCormick & Co. The principal offices were located at 120 Delaware Avenue, just steps from Buffalo City Hall, where we remained for more than 35 years.

Over the next three decades, the Firm grew by developing specialized services, delivering exceptional client service, and completing a series of mergers and acquisitions. We relocated to the Brisbane Building in downtown Buffalo in 1990 and changed our name to Lumsden & McCormick, LLP. In the fall of 2012, after years of planning and careful consideration, the Firm moved to the historic Cyclorama Building, located at 369 Franklin Street.

Today, we continue to build on the solid foundation established by founders Lathan, Lumsden, and McCormick, providing valuable insight and trusted advice to all our clients. We are proud of our rich history, and we look forward to leading the way for generations to come.

Cyclorama Building

According to the Historic American Buildings Survey (HABS No. NY-6297), the Cyclorama Building was built in three short months, opening September 8, 1888. At the time, cyclorama buildings were popping up around the world as a form of entertainment, their purpose to house 'cycloramas,' or panoramic art displays. 

Buffalo's first cyclorama painting hung 50 feet high by 400 feet long in a circular fashion inside the interior walls. There were no windows nor interior walls to the original structure, only skylights and lanterns were used to illuminate the painting as a docent described the scene. The original show, “View of Jerusalem on the Day of the Crucifixion of Christ,” drew thousands of visitors daily for the two years it ran.  The next show, "The Battle of Gettysburg," ran for another two years. Soon after, cycloramas lost their popularity and in 1907, the building was acquired by the City of Buffalo and used as a roller skating rink, livery, and taxi garage. 

By 1937 it fell under such disrepair that the building was condemned. Later that year the building was taken over by the Public Works Administration. Five years later, the building opened as an annex to the Grosvenor Library Reading Room, with newly installed windows and updates to the floors and ceiling. For 21 years the Grosvenor Reading Room hosted lectures, students, and library patrons, including Mr. Charles Lumsden, while studying for his CPA exam. Today the Grosvenor Room is currently housed in the central branch of the Buffalo & Erie County Public Library, housing the library’s special collections.

After closing this branch of the library, the building once again stood vacant until 1985, when Frank Ciminelli purchased the building. With careful attention to preserving the building, no power tools were able to be used on the brickwork and nothing stronger than detergent could be used to clean it, second floor was added and the Cyclorama Building became the offices of Ciminelli Construction Company.   

In September of 2012, Lumsden McCormick moved into the historic Cyclorama Building. Buffalo's Cyclorama Building is one of three remaining cycloramas in the country. A version of "View of Jerusalem on the Day of the Crucifixion of Christ" exists in Quebec's Cyclorama of Jerusalem and "The Battle of Gettysburg" may be seen at the Gettysburg National Military Park Museum and Visitor Center.
