Discovered 1788 by William Herschel.

Besides M102 (NGC 5866), this is the second prominent member of the M102 (NGC 5866) group. As it is seen almost exactly edge-on, and is an extremely flat disc, it appears extremely elongated, shaped like a "knife edge" or a splinter, therefore its popular name.

William Herschel discovered this galaxy together with M102 (NGC 5866) and several fainter galaxies in this celestial area on May 5, 1788, and cataloged it as H II.759.

Supernova 1940A, which was discovered by Johnson, occurred in NGC 5907 on February 16, 1940 and reached magnitude 14.3 (see PASP 52, 146).
