The American Radio Relay League (ARRL) is the largest membership association of amateur radio enthusiasts in the USA. ARRL is a non-profit organization, and was co-founded on April 6, 1914 by Hiram Percy Maxim and Clarence D. Tuska of Hartford, Connecticut.
The 1920s saw tremendous technical growth in radio. Pushed both by wartime demands and by the growing commercialization of radio, equipment rapidly improved. In 1923 a two-way contact between Connecticut and France bridged the Atlantic Ocean for the first time.
With government uncertainty as to how to allocate both commercial and amateur frequencies, the ARRL kept discipline in amateur ranks so that spectrum was not unnecessarily occupied. They worked with Washington and the result was that amateurs received the orderly series of harmonic frequency bands.
Other activities during this time included transcontinental relays to quickly move messages across the United States, communications assistance in several emergencies, and encouragement for an amateur radio operator on an Arctic expedition of Donald B. MacMillan—perhaps the first beginnings of DXpeditions. The League also began to act in an advisory capacity for the American delegations at international radio conferences. In 1925 the International Amateur Radio Union was formed.
A controversial idea was originated in 1961 when the League encouraged "incentive licensing", which sought reversion to the principle that higher levels of license privileges should require higher levels of demonstrated knowledge and CW skill but took away some amateur privileges until licensees requalified at higher levels; "incentives" are still in effect and only holders of the highest class of license (Amateur Extra) maintain all amateur privileges. By 1964 the positive influence of the ARRL was so evident that the United States issued a commemorative postage stamp on its 50th anniversary.
Rand McNally & Co. is a large American map and navigation company best known for its annual atlases. The company got its start in 1856, when William Rand opened a print shop in Chicago. He was joined in 1858 by a new employee, Andrew McNally. Together, the men established their namesake company in 1868. Originally, the company was intended to print the tickets and timetables for the trains running to and through Chicago; their first railway guide was published in 1869.
By 1870, they had shifted from just printing to publishing directories, travel guides, and newspapers. Their first map appeared in 1872 in a railway guide. The map was produced using a new wax engraving method, a cheaper process that gave the company an edge.
By 1880 Rand McNally had entered the education market with globes, wall maps, and geography texts for students. In 1923, Rand McNally published the first Goode’s World Atlas, named after its editor, Dr. J. Paul Goode. For generations afterward, this would be the standard classroom atlas.
In 1899, William Rand left the company, but McNally and his family remained, controlling the company for over a century. In 1904, they published their first road map intended for automobiles and by 1907 were publishing Photo-Auto Guides, which combined photography and mapping to help drivers. In 1924, they produced the Auto Chum, a precursor to their famous road atlases. Rand McNally would remain the leader in road maps and atlases throughout the twentieth century.
In 1937, Rand McNally opened its first store in New York City. Ever on the frontier of technology, Rand McNally pioneered the scribing process for printing tickets in 1958 and printed their first full-color road atlas in 1960. Arthur Robinson developed his now-famous projection of Rand McNally in 1969. By the 1980s, the company was exploring digital reproduction and digital databases of maps for truckers. In the 1990s, they lead the charge to develop trip-planning software and websites. Today, most of its products are available online or in a digital format, including maps for tablets and phones.
