Rutgers has a building named after him, Leonor Fresnel Loree, erected in 1963 on the Douglass campus.

[2] In 1903, Loree, together with Frank PJ Patenall, received U.S. patent 733,981, for the upper quadrant semaphore, which soon became the most widely used form of railroad lineside signal in North America.

In 1906 a committee of creditors asked Leonor to take charge of the Kansas City Southern Railroad.

At the time it was considered no more than "two streaks of rust, its engines lost steam, the men were disheartened and the stations were shacks."

After Mr. Loree gave his initial inspection, in a speech in front of the financial community, he ended his professional and technical description of the railroad line by stating, "This is a helluva way to run a railroad".
