Fun Facts About Glenmont
When originally built, Glenmont was a marvel of modern living, and had:
- A central heating system
- 23 fireplaces
- Hot and cold running indoor water
- Indoor flush toilets
- A refrigerator room in the kitchen
Most of Glenmont’s fireplaces were seldom, if ever used, as the home’s central heating system did the job just fine. Originally, Glenmont had 23 and 1/2 rooms, including 2 and 1/2 baths. The Edison’s added 6 more bathrooms to the home and made many other additions and modifications while living there. Today, the home has 29 and 1/2 rooms.
Soon after buying Glenmont, Edison had it wired for electricity. Power for the mansion was provided by a dedicated line run from his nearby West Orange Laboratories, probably using underground cables very similar to the ones he was using to demonstrate his now legendary Pearl Street electric generating station and distribution system concept in New York City. From about 1888 thru 1958 those DC cables powered the mansion. With the passing of Glenmont into governmental stewardship (the National Park Service) in the late 1950s, new AC wiring finally replaced the old DC system. Remnants of that bygone DC era still can be seen in the basement of the mansion.
Glenmont was originally built using 157,000+ bricks, and 10,000+ pounds of iron and steel framing. It has 91 windows and 7 chimneys; and employs about 40 window awnings. It took two years to build (1880-1882). This massive and elegant building contains 20,000 square feet of living area. Glenmont measures approximately 123 feet long (north to south), 116 feet wide (east to west), and 54 feet high. It has a 23 foot square open porch at its top (a widow’s walk), from which New York City can be seen. It has a magnificent conservatory that dominates its southern face.
Originally, all the rainwater from the roof gutters of Glenmont was directed to four underground cisterns, built into the foundation, which then were used to supply water to the flush toilets in the home, pumped to and then dispensed from a central tank in the attic.
Glenmont is now heated and cooled using a natural earth energy system called geothermal heating. In the summer, heat from the house is extracted and stored down twelve, 350 foot deep wells, about 200 feet away from the house. In the winter, this heat is retrieved and used to heat the house. It all works on the same principle as the refrigerator. Six heat pumps do all the work in capturing and moving the heat between the house and its storage wells. A geothermal alternate energy system was chosen for installation during the home’s massive renovation in 2004-05 as a way to recognize the Edison’s respect and love for nature–she being an ardent environmentalist, horticulturist, and conservationist; and he using many natural materials in his inventions, as well as enjoying camping and nature tours.
Art & Architecture of Glenmont
Glenmont was designed by famed architect Henry Hudson Holly. Holly is also known for designing another famous American historical figure’s house – Mark Twain. On the first floor of Glenmont, each room is lavishly decorated in different types of wood:
- Grand entrance: mahogany and oak
- Sitting room: birch
- Drawing room: rosewood
- Library: dark mahogany
- Dining room: ash
- Den: primavera
Thomas Edison and his wife Mina were also great lovers of art.
Glenmont generally needed 4-6 servants to keep it running; and sometimes as many as 10 if a large affair was being hosted. People from all over the world worked there. Edison referred to his international staff as “his league of nations”, and they lived and worked in close proximity to the family, having their quarters on the third floor of the home.
[Photo (below)- What was originally the back entrance to the home was modified circa 1915 and made into a lovely tea or contemplation room for Mina. Taking later western sun she would read or greet friends in this delightful nook.]
Is there a pipe organ in the Edison home? If so, are there any pictures and specifications of the instrument.
Here below is how to contact the Thomas Edison National Historical Park to get more information about the pipe organ in the Edison historic home [Glenmont].

What’s Happening i am new to this, I stumbled upon this I have discovered It absolutely helpful and it has aided me out loads. I am hoping to give a contribution & help other users like its aided me. Good job.
Thank you for the kind words! Tell your friends about us too, especially teachers. We always add new materials to the site.
Who had the house built, furnished, and lived in the house prior to Edison purchasing the property in 1886??? Please & Thank you.
The man was Henry Pedder a secretary for the Arnold Constable Company in NYC. He had stolen funds from the company, about $300,000, to build the beautiful mansion now known as Glenmont. In 1884 he was jailed for his crime and the company sold the house fully furnished to Mr. Edison for $125,000, including all acreage and outlying buildings. The house was a wedding gift to his lovely bride Mina.
You actually make it seem so easy with your presentation but I find this matter to
be actually something which I think I would never understand.
It seems too complicated and extremely broad for
me. I’m looking forward for your next post, I will try to get
the hang of it!
I see that Edison wired his house for electricity (DC of course) from the labs. But what was the fuel for the generators? Was it run off diesel oil? Did he use his Ni-Fi batteries in the process?
So what happened to Henry C. Pedder? Did he move back to the West indies? An H. C. Pedder wrote some essays that were published, the latest one in 1902 but if he did return to the West Indies, there is a record saying a Pedder owned the Babbs Plantation in St. Lucie around 1913.

It would be lovely to see the Edison estate person to person. I’m doing research at my local public library about field trips for the Science and the history classes, clubs at my area school. I should know about how far Menlo Park is from the Edison estate and house and home real soon.:)
this is a nice home
