[i] “…Johannes Gutenberg…”

“Johannes Gensfleisch zur Laden zum Gutenberg (c. 1400 – February 3, 1468) was a German goldsmith and printer, who is credited with inventing movable type printing in Europe (c. 1439) and mechanical printing globally. His major work, the Gutenberg Bible, also known as the 42-line bible, has been acclaimed for its high aesthetic and technical quality.

Although Gutenberg was financially unsuccessful in his lifetime, the printing technologies spread quickly, and news and books began to travel across Europe much faster than before. It fed the growing Renaissance, and since it greatly facilitated scientific publishing, it was a major catalyst for the later scientific revolution. Gutenberg is thought to have said: “Give me 26 soldiers of lead and I shall conquer the world.”

Printing was also a factor in the Reformation: Martin Luther found that the 95 Theses, which he posted on the door of his church, were printed and circulated widely; subsequently he also issued broadsheets outlining his anti-indulgences position (ironically, indulgences were one of the first items Gutenberg had printed). The broadsheet evolved into newspapers and defined the mass media we know today.”

[ii] “…George Washington Carver…”

“George Washington Carver (July 12, 1864 – January 5, 1943) was an American botanical researcher and agronomy educator who worked in agricultural extension at the Tuskegee Institute in Tuskegee, Alabama, teaching former slaves farming techniques for self-sufficiency.

George Washington Carver reputedly discovered three hundred uses for peanuts and hundreds more uses for soybeans, pecans and sweet potatoes. Among the listed items that he suggested to southern farmers to help them economically were adhesives, axle grease, bleach, buttermilk, chili sauce, fuel briquettes, ink, instant coffee, linoleum, mayonnaise, meat tenderizer, metal polish, paper, plastic, pavement, shaving cream, shoe polish, synthetic rubber, talcum powder and wood stain. Three patents (one for cosmetics, and two for paints and stains) were issued to George Washington Carver in the years 1925 to 1927; however, they were not commercially successful in the end. Aside from these patents and some recipes for food, he left no formulas or procedures for making his products. He did not keep a laboratory notebook.

Carver’s most important accomplishments were in areas other than industrial products from peanuts, including agricultural extension education, improvement of racial relations, mentoring children, poetry, painting, religion, advocacy of sustainable agriculture and appreciation of plants and nature. He served as a valuable role model for African-Americans and an example of the importance of hard work, a positive attitude and a good education. His humility, humanitarianism, good nature, frugality and lack of economic materialism have also been widely admired.

One of his most important roles was that the fame of his achievements and many talents undermined the widespread stereotype of the time that the black race was intellectually inferior to the white race. In 1941, “Time” magazine dubbed him a “Black Leonardo”.

[iii] “…Jonas Salk…”

“Jonas Edward Salk (October 28, 1914 – June 23, 1995) was an American biologist and physician best known for the research and development of the first effective polio vaccine.

While being interviewed by Edward R. Murrow on “See It Now” in 1955, Salk was asked: “Who owns the patent on this vaccine?” Surprised by the question’s assumption of the requirement of a profit-motive for his creation, he responded: “There is no patent. Could you patent the sun?”

[v] “… Renaissance…”

The Renaissance (from French Renaissance, meaning “rebirth”; Italian: Rinascimento, from re- “again” and nascere “be born”) was a cultural movement that spanned roughly the 14th through the 17th century, beginning in Italy in the late Middle Ages and later spreading to the rest of western Europe. It encompassed a revival of learning based on classical sources, the development of linear perspective in painting, and educational reform. The Renaissance saw developments in most intellectual pursuits, but is perhaps best known for its artistic aspect and the contributions of such polymaths as Leonardo da Vinci and Michelangelo, who have inspired the term “Renaissance men”.

However,  it was not until the nineteenth century that the French word Renaissance achieved popularity in describing the cultural movement that began in the late 13th century”  (1200 AD – 1300 AD).

The term was first used retrospectively by the Italian artist and critic Giorgio Vasari (1511-1574) in his book The Lives of the Artists (published 1550). In the book Vasari was attempting to define what he described as a break with the barbarities of gothic art: the arts had fallen into decay with the collapse of the Roman Empire and only the Tuscan artists, beginning with Cimabue (1240-1301) and Giotto (1267-1337) began to reverse this decline in the arts. According to Vasari, antique art was central to the rebirth of Italian art.

During the 12th century in Europe, there was a radical change in the rate of new inventions and innovations in the ways of managing traditional means of production and economic growth. In less than a century, there were more inventions developed and applied usefully than in the previous thousand years of human history all over the globe. The period saw major technological advances, including the adoption or invention of printing, gunpowder, spectacles, a better clock, the astrolabe, and greatly improved ships. The latter two advances made possible the dawn of the Age of Exploration.

Alfred Crosby described some of this technological revolution in The Measure of Reality : Quantification in Western Europe, 1250-1600 and other major historians of technology have also noted it.
