Great Inventions
PAPER – invented about 100 BC in China, paper has been indispensible in allowing us to write down and share our ideas.
GUNPOWDER – this chemical explosive, invented in China in the 9th century, has been a major factor in military technology (and, by extension, in wars that changed the course of human history).
PRINTING PRESS – invented in 1439 by the German Johannes Gutenberg, this device in many ways laid the foundation for our modern age. It allowed ink to be transferred from the movable type to paper in a mechanized way. This revolutionized the spread of knowledge and religion as previously books were generally hand-written (often by monks). ELECTRICITY – utilization of electricity is a process to which a number of bright minds have contributed over thousands of years, going all the way back to Ancient Egypt and Ancient Greece, when Thales of Miletus conducted the earliest research into the phenomenon. The 18th-century American Renaissance man Benjamin Franklin is generally credited with significantly furthering our understanding of electricity, if not its discovery. It’s hard to overestimate how important electricity has become to humanity as it runs the majority of our gadgetry and shapes our way of life. The invention of the light bulb, although a separate contribution, attributed to Thomas Edison in 1879, is certainly a major extension of the ability to harness electricity. It has profoundly changed the way we live, work as well as the look and functioning of our cities.

Who is the Greatest Teacher in History?
William McGuffey
Another teacher, who, like Montessori, was able to develop his theories about child education into a workable practical system, was William Holmes McGuffey. His series of readers would have a profound impact on education in America and on educational books in general. William McGuffey was born in 1800 and was a precocious child. He was such an adept student, in fact, that he began to teach classes himself at the age of 14. Putting in long hours at country school houses in Ohio and Kentucky, McGuffey saw that there was no standard method to teach students how to read; in most cases, the Bible was the only book available.
McGuffey paused his teaching career to attend college himself, and by age 26, he had been appointed Professor of Languages at Miami University in Oxford, Ohio. His ideas about language teaching were much admired by his colleagues, and in 1835, through the intercession of his friend Harriet Beecher Stowe, he was asked to write a series of readers for the publisher Truman and Smith.
McGuffey’s readers, more correctly known as Eclectic Readers, set a template for textbooks that we still follow today. They followed a steady progression from the first reader through the fourth, beginning with teaching of the alphabet and phonics alongside simple sentences, and progressing all of the way up to poems and stories. Vocabulary was often taught in context rather than as lists of words, and questions after the stories, as well as read-alouds, encouraged students to interact with what they read. The content was lively and the presentation crisp.
