The photographer Theodor Horydczak admires the jewel-like pyramid of aluminum on top of the Washington Monument

 

Little is known about Horydczak himself. He is believed to have been born in eastern Europe, and to have taken up photography during or after World War I, possibly while a member of the U.S. Army Signal Corps. His residence in Washington spanned the period from the early 1920s to his retirement in 1959.

 

Horydczak's studio logbook opens with a 1921 entry for a photograph of cherry blossoms along the Tidal Basin.

The 100 ounce (2.8 kg) aluminium capstone was put in place on December 6, 1884,

 

Aluminium has the symbol Al; its atomic number is 13. It is the 3rd most abundant element.

 

Oxygen, Silicon, Aluminum

 

The chief source of aluminium is bauxite ore.

 

Although aluminium is the most abundant metallic element in the Earth's crust, it is rare in its free form, occurring in oxygen-deficient environments such as volcanic mud, and it was once considered a precious metal more valuable than gold.

 

Bauxite, the most important ore of aluminium, contains only 30-54% alumina, Al2O3, the rest being a mixture of silica, various iron oxides, and titanium dioxide. The alumina must be purified before it can be refined to aluminium metal. In the Bayer process, bauxite is digested by washing with a hot solution of sodium hydroxide, NaOH, at 175 °C. This converts the alumina to aluminium hydroxide.

 

Today the Bayer process marks the birth of the modern field of hydrometallurgy.

On this same day the King of the Hawaiian Islands granted the United States the exclusive right to enter the harbor of the Pearl River in the Island of Oahu.

In 1884, 41 delegates from 25 nations attended the International Meridian Conference in Washington, D.C.United States to determine the Prime Meridian of our planet. The conference was held at the request of U.S. President Chester A. Arthur. It would be interesting to see if there is any correlation to the Inauguration of the Washington Monument.

The one touching the cap looks mysterious wearing those sunglasses.

Here is an excerpt of George Wasington's letter to the To the Hebrew Congregation in Newport, Rhode Island.

 

 

Newport, R.I., 18 August 1790

 

 

May the Children of the Stock of Abraham, who dwell in this land, continue to merit and enjoy the good will of the other Inhabitants; while every one shall sit in safety under his own vine and figtree, and there shall be none to make him afraid. May the father of all mercies scatter light and not darkness in our paths, and make us all in our several vocations useful here, and in his own due time and way everlastingly happy.

 

Go: Washington

When George Washington died, on December 14, 1799, there was throughout America a profound outpouring of grief at our loss, gratitude for his life, and deep reverence for his memory. "For two months after Washington’s burial at Mount Vernon, his countrymen continuously expressed their bereavement in private correspondence, in resolutions of Congress and of State legislatures, in town meetings, in the pages of newspapers and, most singularly, in hundreds of funeral processions and solemn eulogies in every corner of the nation.

My question is whether what is stated as the Washington Monument capstone is really a finial or pyramidion?

Author George J. Binczewski, in his seminal work: The Point of a Monument: A History of the Aluminum Cap of the Washington Monument would have us believe it is neither, as he refers to the very top of the Washington Monument as the "aluminum pyramid cap ... at the apex [of the monument]."

 

Also of note is: the **entire** time I was growing up in DC (40 years +) I was always led to believe the Washington Monument was "tipped by two platinum lightning rods 555 feet 5 inches above the National Mall."

 

So much for Urban Legend...
