Alfred j gross family biography

The exact dates that she was there are not known. When she was orphaned, her sister would have been too old for the orphan home. So, perhaps she lived there for a time after her mother died. However, the records for the home do not list the Droessler children. The General Protestant Orphan Home took kids below the age of 16 and had a horse, cows, hogs, and a greenhouse.

The girls were taught domestic duties and the boys were taught trades, one of which was shoe repair. Henry was later a cutter at a shoe factory, so probably he learned that trade at the home. Her older sister also worked at a shoe factory. Sophia was eleven when she was orphaned. Her oldest sibling, Charles, was twenty-two. Mollie would have been twenty, Henry, fourteen, and Georg, ten.

Charles was given custody, but not until Sophia stayed in school only until grade five, when she would have been about So, presumably she left school when her father died. Mollie and John had a daughter, Edna, on March 16, Sophia was listed in the Williams Street Directory, but no occupation was noted. Her brothers were both shoe workers.

Sophia married Alfred J. Gross between and He was one year her senior. It could be that they met when they each attended a wedding of mutual friends on June 11, Albert worked as a salesman at a store located on the corner of Elder and Race Streets. Sophia and Alfred lost their first child, Edith, in just after she was born. They had three more children in the coming years: Alfred Jr.

He will be missed, the following past articles are a tribute to his many accomplishments. Retro-Dave Retrocom is proud to bring you several articles about one of radio communications modern day pioneer's. Further research into the work of Mr. Gross has verified that he is indeed the Father of CB radio. A case could also be made that the F.

Al Gross Biography. Al Gross is a true pioneer of the wireless personal communications revolution and played a major role in establishing miniaturized portable communications. He also successfully lobbied the Federal Communications Commission FCC to create the Personal Radio license spectrum in , which later became citizens band radio. In at age 16 Al obtained his amateur radio license, and it is still current today.

At the time, portable wireless communications did not exist, and very little knowledge about radio communications, circuits, designs, and propagation existed above megahertz. Frequencies above MHz is where Al focused his development efforts. He developed circuits and components for miniaturized portable communications that were unheard of for that era.

He also succeeded in the design and construction of several battery-operated, portable, hand-held transceivers with corresponding compact antennas. Two of the models operated at megahertz These two hand-held models were used many times to successfully communicate with other amateur operators over a distance of 30 miles. From this meeting, the "Joan Eleanor" two-way radio system was proposed allowing OSS agents in occupied countries and Germany to communicate with two-way radio equipment in high-flying aircraft.

Al headed up this project and developed a sensitive receiver circuit that could be miniaturized. Al met with Major E. Armstrong late in at his office in Alpine, New Jersey. Armstrong suggested a super regenerative circuit that could be used, and Mr. Gross implemented this concept with modification in both the transmitter and receiver. Jett published an article "Phone by Air" in the Saturday Evening Post July describing personal two-way radio communications for the public use.

Gross launched Citizens Radio Corporation to design, develop and manufacture personal wireless transceivers and also started Gross Electronics to design and build other communications products. Gross Electronics was under contract to test and develop life saving equipment for emergency use for the U. Maritime Commission and the War Shipping Administration.

In the company was contracted by the U. Coast Guard to design and build a hand-held transceiver operating at megahertz TRC Grosoli, Giovanni. Grosman, Ladislav. Grosjean, Paul. Grosjean, Jean Romary. Grosjean, Ernest. Grosjean v.

They communicated with each other through Hertzian radio waves, working at MHz, which enemies could not penetrate.

The units had a roughly mile range. The ground unit had a transceiver weighing just three-and-a-half pounds, a collapsible antenna, and two B and two D batteries for power. The U. Joint Chiefs of Staff called it among the best intelligence-gathering methods ever. In and , the last two years of World War II , intelligence teams in the Netherlands and Germany were able to signal Mosquito planes six miles above them.

When World War II ended, Gross launched Gross Electronics, which designed and constructed communications products, including those under government contract. Gross also founded Citizens Radio Corporation, which made personal wireless receivers, after the Federal Communications Commission FCC allocated him frequencies for personal radio service.

Gross himself sold roughly , units, mostly to farm owners and to the U. Coast Guard. In addition, he licensed the technology to electronics companies. He also gave cartoonist Chester Gould permission to use Gross's concoctions in his detective comic strip Dick Tracy , paving the way for the Dick Tracy two-way radio. Gross surfaced with yet another innovation in He adapted the two-way radios for cordless remotes.

Doctors were initially the inventor's target group, but he faced initial resistance while marketing it at a medical convention in Philadelphia, Pennsylvania. The pagers caught on, however; an estimated million were sold worldwide in Throughout the s, Gross vainly attempted to sell U. The FCC, though, did approve his pager transceivers in In the s, such companies as Sperry and General Electric hired Gross as a consultant for microwave and other communications systems after Gross gave up as an entrepreneur.

In addition, he provided technology for digital timing devices for Titan, Atlas, and Minuteman missiles while the aerospace industry was in massive growth mode. Gross, who enjoyed teaching, frequently discussed technology and invention with elementary and high school students. The patents on Gross's technologies expired in Accolades poured in over the years, including a commendation from President Ronald Reagan in Gross also received the Fred B.

Gross worked during the s as an electrical engineer at Orbital Sciences Corporation in Chandler, Arizona. There he worked on space exploration programs, overseeing the analysis of electromagnetic elements of satellite, military, and aerospace systems. Gross kept himself busy and had little spare time. His hobbies included visiting Civil War battlegrounds and searching for relics.

Not surprisingly, he designed his own metal detector.
