The First Regenerative Circuit

Edwin Howard Armstrong was born in New York City in December 1890. Illness as a child left him withdrawn and he was attracted to engineering. He attended Columbia University and was attracted to the new field of Radio which was in it’s infancy. Tesla had experimented in the 1890 and Marconi copied his work and was beginning to work in wireless transmissions. In 1906 Lee De Forest invented the Audion, a vacuum tube that greatly electrical signals for radio. De Forest made the first ship to shore radio transmission in 1907 and the first public radio broadcast of the opera TOSCA from the New York Metropolitan Opera in 1910. De Forest invented the term “Radio” based on the “radiating signals” of the device.

Armstrong, a 21 year old electrical engineering student, was working at Columbia University’s School of Engineering on the Audion when he realized that he could amplify faint radio signals by repeatedly feeding current through the relatively new Audion grid and boost their power dramatically. This was called Positive Feedback. This was the first regenerative circuit.

On September 22, 1912 Edwin Armstrong made the first successful test of the regenerative circuit. It is revolutionary in the way it amplifies radio waves and promises to make the reception of voice messages without wires a practical, affordable reality.

First Eagle Scout Award Approved

The Boy Scouts of America highest award was originally the Wolf Scout. In August 1911 it was changed to Eagle Scout. Eagle Scout was not a rank, but part of the merit badge system that recognized Scouts who had earned a specified number of merit badges. Eagle Scout was awarded to any First Class Scout who had earned 21 merit badges. Arthur Rose Eldred had completed the 21 merit badges required for Eagle Scout in April 1912. In the beginning of August 1912 the first Eagle Scout board of review was held at the time when only 141 merit badges had ever been earned by about only 50 US Scouts.

On August 12, 1912 Arthur Rose Eldred became the first Eagle Scout in the Boy Scouts of America.

Cosmetic Innovator Patents New Powder Box

Joseph Angiolini Pozzoni was an Englishman of Italian extraction who arrived in New York between 1840 and 1850. He worked as a hairdresser at a time when cosmetics were frowned upon and only used by women of “loose character”. In 1860 he started manufacturing face powder as a supplement to his hair dressing. After serving in the Civil War heconcentrated on cosmetic products ranging from powders, face creams, hair wash, tooth powder and extracts for handkerchiefs. He was always potryed in his Army uniform.

Pozzoni died in 1885 but under his wife’s guidance to company went on and grew. Pozzoni’s was one of the first companies to use the whole range of media available at the time including magazines, postcards, calendars, paper dolls and celebrity endorsements. Ziegfeld girl Anna Held was used in advertisements. Pozzoni Company was also innovative in packaging introducing the first “vanity case” in 1894 with the Gold Puff Box demonstrating that the container could help sell the product more readily than the contents. It was a huge success.

On July 9, 1912 Pozzoni’s patented a new design of facial powder box. It was was sold with a wooden container of face powder, a small cardboard rouge box and a chamois cloth.

Baby Plate Patented

Baby high chairs may have been around since ancient times in one form or another. Joseph W Kenna was granted a patent for a child’s high chair and carriage in February 1880.

On June 11, 1912 Underwood patented a plate especially designed for high chairs. It had a wide triangular bottom to prevent being tipped over easily.
