Inventions and Science
The idea of the stop sign was first invented in 1890. Though not put into use until 1915, William Phelps Eno from Saugatuck, Connecticut published an article in Rider and Driver suggested the first set of traffic laws. The first stop signs were white with black text, but have been changed over the years and, of course, are still the same things we use today.
Smoke detectors were invented in 1890 by Francis Robbins Upton and Fernando J. Dibble. Again, this invention, although new and improved, is still in use today.
In 1892 William Painter of Baltimore Maryland invented the bottle cap.
The first gasoline powered tractor was invented in 1892 by John Froelich in Clayton County, Iowa.
The first Henry Ford vehicle, the quadricycle, was completed on June 4th, 1896, but they weren't able to test drive it because it was too big to fit out the door of the vehicle it was built in.
Stewart Halstead invented the first medical gloves in 1894. These gloves helped to prevent the spread of disease and make all medical procedures sterile in ways that were not possible before.
Volleyball, originally known as "Mintonnette" was invented by William G. Morgan in 1895. Alfred S. Halstead later renamed the Olympic sport Volleyball.
Milton O. Reeves invented the internal combustion engine muffler in 1897.
Nickel-Zinc batteries are a type of rechargeable battery which were invented by Thomas Alva Edison in the year 1900.
All throughout the decade Thomas Alva Edison worked on moving pictures. In 1891 the kinetoscope was invented so that one person could view a moving picture. In 1896 the vitascope came about so that moving pictures could be projected to multiple people. In fact, the first ever cat video was recorded in 1890 by Etienne-Jules Marey.
This decade brought fourth so many ideas and innovations that the commissioner of the U.S. Patent Office, Charles Duell said "Everything that can be invented has been invented!" in 1899.
