Martin Cooper, who turns 82 on December 26th, is an electrical engineer – having gained his Master’s degree from the Illinois Institute of Technology in 1957.

Cooper’s inspiration for undertaking the project was the Star Trek television series, in which a small, hand-held ”communicator” device was used very much in the manner of a portable phone.

As I walked down the street while talking on the phone, sophisticated New Yorkers gaped at the sight of someone actually moving around while making a phone call. Remember that in 1973 there weren’t cordless telephones, let alone cellular phones. I made numerous calls, including one where I crossed the street while talking to a New York radio reporter – probably one of the more dangerous things I have ever done in my life.

William Wrigley Jr. was born in Philadelphia in 1862, at the height of the Civil War. His father, William, Sr., was a soap manufacturer, and as a little boy, young William carried a basket through the streets of Philadelphia, selling Wrigley's Scouring Soap. When he became a teenager, William took a full-time job as a soap salesman for his father. He had a talent for salesmanship, and he drove a horse and wagon from town to town, trying to convince stores to stock Wrigley's soap. William Wrigley Jr. struck out on his own in the spring of 1891 when he was 29 years old. He left Philadelphia for Chicago with just $32 in his pocket and a dream of running his own business. He also had boundless energy and a gift for seeing things from his customers' point of view.

He was born Francis Factor in St. Louis, Missouri, the son of Max Factor, a Polish immigrant. Known as "Frank," his family moved to Los Angeles, California, in 1908 where he began working in the family business while still a boy.

While his father wanted to reserve the product for film use, Frank Factor was open to the commercial possibilities and began developing lighter shades.

At the time the company was only able to produce enough to meet studio demand which until production could be increased delayed commercial release until 1937.

Martin Cooper, byname Marty Cooper   (born December 26, 1928, Chicago, Illinois, U.S.), American engineer who led the team that in 1972–73 built the first mobile cell phone and made the first cell-phone call. He is widely regarded as the father of the cellular phone.

He joined the U.S. Navy and served during the Korean War. After the war, he joined the Teletype Corporation, and in 1954 he began working at Motorola.

On April 3, 1973, Cooper introduced the DynaTAC phone at a press conference in New York City. To make sure that it worked before the press conference, he placed the first public cell-phone call, to engineer Joel Engel, head of AT&T’s rival project, and gloated that he was calling from a portable cellular phone.

American engineer Martin Cooper (born 1928) is often dubbed the father of the mobile phone. In November of 1972, he and a team of associates at the Motorola Company began working on a prototype of the Dyna-Tac phone, and five months later Cooper stood on a Manhattan street and placed the world's first call from a mobile phone. “There were a lot of naysayers over the years,” Cooper admitted in an interview with Investor's Business Daily writer Patrick Seitz. “People would say, ‘Why are we spending all of this money? Are you sure this cellular thing will turn out to be something?’ ”

William Procter and James Gamble settle in the Queen City of the West, Cincinnati, and establish themselves in business — William as a candle maker and James as a soap maker. The two might never have met had they not married sisters, whose father convinced his new sons-in-law to become business partners. As a result, in 1837, a new company was born: Procter & Gamble.

1879 P&G launches its first branded product, Ivory Soap.

P&G becomes one of the first companies to advertise on commercial radio.
