Famous quotes containing the word history:
“There is a history in all mens lives,
Figuring the natures of the times deceased,
The which observed, a man may prophesy,
With a near aim, of the main chance of things
As yet not come to life.”
—William Shakespeare (15641616)
“I believe my ardour for invention springs from his loins. I cant say that the brassiere will ever take as great a place in history as the steamboat, but I did invent it.”
—Caresse Crosby (18921970)
“The second day of July 1776, will be the most memorable epoch in the history of America. I am apt to believe that it will be celebrated by succeeding generations as the great anniversary festival. It ought to be commemorated, as the day of deliverance, by solemn acts of devotion to God Almighty. It ought to be solemnized with pomp and parade, with shows, games, sports, guns, bells, bonfires and illuminations, from one end of this continent to the other, from this time forward forever more”
—John Adams (17351826)
