In America, he was educated at Mount Pleasant Classical Institute and one of his teachers included Gregory Anthony Perdicaris.

At the academy, he also met Chauncey Colton whom he followed around the country to different educational institutions one was outside of Philadelphia and the latter was Kenyon College in Gambier Ohio.

Zachos attended Kenyon College and graduated with honors and also obtained a medical degree but did not practice medicine because of his love for literature and teaching.

Zachos became a Unitarian Minister, briefly taught at Cornell, and finally settled in New York City where he was the curator of the library at Cooper Union and a professor at the institution until his death.

He brought John Celivergos Zachos along with other young Greek people back to the United States to educate them.

In 1851, he wrote a book on his travels called The Greek Exile, Or, a Narrative of the Captivity and Escape of Christophorus Plato Castanis.

Their instructors were Gregory Anthony Perdicaris and Petros Mengous and the assistant principal and founder was Chauncey Colton D. D.[12][14] Zachos later traveled to an Episcopalian institution twenty miles north of Philadelphia.

[16] Zachos, Stanley Matthews (judge), Ainsworth Rand Spofford, and nine others founded the Literary Club of Cincinnati in 1849.

Other prominent members included William Howard Taft and notable club guests Ralph Waldo Emerson, Booker T. Washington, Mark Twain, and Robert Frost.

Harriet's second cousin John Caldwell Canfield married Ella Todd, Abraham Lincoln's niece.

[20] By 1850, Zachos was the co-owner and principal of the Cincinnati Female Seminary on the southeast corner of Ninth and Walnut.

During the early 1850s Zachos wrote several books: The New American Speaker and Introductory Lessons in Reading and Elocution.

[21] Educator Horace Mann, a fellow Bostonian and close friend to Samuel Gridley Howe, took a position at Antioch College in Yellow Springs, Ohio.

By 1857 Zachos moved back to Cincinnati he took random teaching jobs and wrote four more books before the onset of the Civil war.

[22] At the onset of the Civil War, Zachos was summoned by close friend Salmon P. Chase to go to Port Royal.

Ye sons of burning Afric's soil, Lift up your hands of hardened toil Your shouts from every hill recoil Zachos left Parris Island towards the end of 1863 to conclude the experiment.

The students had to wait until March 1864 to receive the first book which had an extremely long title The Phonic Primer and Reader, A National Method of teaching Reading by the Sounds of the Letters without altering the Orthography.

Designed Chiefly for the Use of Night-Schools Where Adults are Taught, and for the Myriads of Freed Men and Women, Whose First Rush from the Prison-House of Slavery is to the Gates of the Temple of Knowledge.

The method employed a unique phonic education technique of teaching English reading by sounds of letters.

Samuel Gridley Howe traveled back to Greece to carry relief to the Cretan refugees and Zachos moved to Meadville Lombard Theological School.

American author, historian, and Unitarian minister Edward Everett Hale spoke very highly of John C.

He accepted the call and began his ministry here at the beginning of May, at a salary of $1500, in addition to the rents of the minister's house, and with four weeks' annual vacation."

He was a versatile man, with an uncommonly wide range of interests; a Greek in temperament as well as by birth, fond of abstract themes, and inclined to consider subjects rather from the philosophical or speculative than from the practical side.

Mr. Zachos resigned in July, 1868, and left Meadville at the beginning of October, in order to accept a call to the church at Ithaca, N. Y.

Peter Cooper told William Cullen Bryant to personally observe Professor Zachos's lecture.

Under the pseudonym "Cadmus" Dr. Zachos wrote about financial and economic subjects that were published in various New York City publications.

Among the many in attendance were his pallbearers S. Packard, Augustus D. Juilliard Former NYC mayor William Lafayette Strong and Union army brevet brigadier general Henry Lawrence Burnett.
