Arthur Atwater Kent, Sr. (December 3, 1873 – March 4, 1949) was an American inventor and prominent radio manufacturer based in Philadelphia. In 1921, he patented the modern form of the automobile ignition coil.

Arthur Kent was born on December 3, 1873, in Burlington, Vermont.

The Kent family moved to Worcester, Massachusetts, in 1881, where they lived at four different locations. His father was a doctor who had also been a machinist. The father maintained a machine shop in Worcester when Arthur was a child. Kent entered Worcester Polytechnic Institute’s freshman mechanical engineering class in the fall of 1895. He was elected treasurer of the class of 1899, but only remained in the position for one semester, because he did not attend recitation classes after the mid-year exams in January. Kent excelled in mechanics and drawing, but was weak in chemistry, algebra and language, and had no interest in these subjects. He was already running a small business and that was his top priority. His business was called the Kent Electric Manufacturing Company, which he began in the back room of his father’s machine shop, and from which he sold small electric motors, generators, fans, and later automobile ignition systems. The Unisparker Ignition systems became the automobile industry standard for almost 50 years, until the advent of the HEI systems.

In 1921, Kent produced his first radio components, selling the do-it-yourself kits consisting of "breadboards" that could be assembled by early radio enthusiasts. The same year, he introduced the Model 5, primarily as a promotional tool. In 1923, his firm started producing complete radio sets, using a facility on Stenton Avenue, introducing the Model 10 for Christmas that year. This was followed by the Model 9 "and a broad line of breadboard sets". In 1924, the company moved to a new $2 million plant at 4745 Wissahickon Avenue in North Philadelphia. This plant, constructed in sections, would eventually cover 32 acres (13 ha).

In 1925, the Atwater Kent Manufacturing Company became the largest maker of radios in the United States. The company also sponsored the popular "Atwater Kent Hour", a top-rated radio concert music program heard on NBC and CBS from 1926 to 1934. The show featured top entertainment and became one of the most popular and acclaimed regular radio programs of the era. At its peak in 1929, the company employed over 12,000 workers manufacturing nearly one million radio sets. Its models included the metal-cabinet seven-tube Model 57 at US$105 and the wooden-cabinet eight-tube Model 60 at US$80. The plant itself was an architectural sensation and received hundreds of visitors annually. By 1931, the company boasted that it had produced over three million radios.
