Spencer’s first microscopes were available for purchase in 1838. Previous to
Spencer’s invention, European manufacturers held a monopoly on research-quality microscopic equipment. At least one of Spencer’s microscopes survives and is currently held by the Smithsonian Institution.

In 1884, ground was broken in
Rochester, NY for the foundation of a monument to Spencer and his peer, Robert B. Tolles to provide an enduring honor of their achievements in American microscopy, and the scientific advances that grew from it.
