History Glen Rock was formed on September 14, 1894, from portions of Ridgewood Township and Saddle River Township during the "Boroughitis" phenomenon then sweeping through Bergen County, in which 26 boroughs were formed in the county in 1894 alone.Snyder, John P.

"For a period of sixteen years following the passage of this act few boroughs were organized in the State, only three of them being in Bergen County.... As it was twenty-six boroughs were created in the county from January 23, 1894, to December 18, of the same year." The main impetus for the break from Ridgewood Township was the decision to have Glen Rock students attend a new school closer to the center of Ridgewood instead of their one-room schoolhouse located at the intersection of Ackerman Avenue and Rock Road. Originally, the borough was to be named "South Ridgewood", but the name was changed to Glen Rock before the proposal for the borough was submitted. Both the origin of the name Glen Rock and the cause of it becoming the borough's name are unclear.

The borough was settled around the Glen Rock, a large boulder in a small valley (glen), from which the borough gets its name.Hutchinson, Viola L.

Accessed August 31, 2015. The rock, a glacial erratic weighing in at and located where Doremus Avenue meets Rock Road, is believed to have been carried to the site by a glacier that picked up the rock 15,000 years ago near Peekskill, New York, and carried it for to its present location. The Lenape Native Americans called the boulder "Pamachapuka" (meaning "stone from heaven" or "stone from the sky") and used it for signal fires and as a trail marker.Elder, Janet. "If You're Thinking of Living in Glen Rock", The New York Times, May 5, 1985. Accessed October 26, 2016. "Glen Rock is named for a 570-ton boulder, believed to have been deposited by a glacier, that stands at the northern end of Rock Road, the town's main street. Called Pamackapuka, or Stone from Heaven, by the Delaware Indians, it served as a base for Indian signal fires and later as a trail marker for colonists."Coutros, Evonne.

The borough was the site of one of Bergen County's most serious public transportation accidents. In 1911, a trolley operator for the North Jersey Rapid Transit Company, one day away from retirement, died in a crash with an opposing trolley around the intersection of Prospect and Grove Streets that was caused by signal problems. In addition to the death of the opposing trolley operator, 12 people were injured. This crash in part hastened the demise of this transportation mode which ran from Elmwood Park, New Jersey, to Suffern, New York, and competed with the Erie Railroad. The right of way for this trolley line was purchased by the Public Service Enterprise Group and is still visible today.Smith Jr., Don E.
