History

Scientific American was founded by inventor and publisher Rufus Porter in 1845 as a four-page weekly newspaper. The first issue of the large-format New York City newspaper was released on August 28, 1845.

Throughout its early years, much emphasis was placed on reports of what was going on at the U.S. Patent Office. It also reported on a broad range of inventions including perpetual motion machines, an 1860 device for buoying vessels by Abraham Lincoln, and the universal joint which now can be found in nearly every automobile manufactured. Current issues include a "this date in history" section, featuring excerpts from articles originally published 50, 100, and 150 years earlier. Topics include humorous incidents, wrong-headed theories, and noteworthy advances in the history of science and technology. It started as a weekly publication in August 1845 before turning into a monthly in November 1921.

Porter sold the publication to Alfred Ely Beach, son of media magnate Moses Yale Beach, and Orson Desaix Munn, a mere ten months after founding it. Editors and co-owners from the Yale family included Frederick C. Beach and his son, Stanley Yale Beach, and from the Munn family, Charles Allen Munn and his nephew, Orson Desaix Munn II. Until 1948, it remained owned by the families under Munn & Company. Under Orson Munn's grandson, Orson Desaix Munn III, it had evolved into something of a "workbench" publication, similar to the 20th-century incarnation of Popular Science.

In the years after World War II, the magazine fell into decline. In 1948, three partners who were planning on starting a new popular science magazine, to be called The Sciences, purchased the assets of the old Scientific American instead and put its name on the designs they had created for their new magazine. Thus the partners — publisher Gerard Piel, editor Dennis Flanagan, and general manager Donald H. Miller Jr. essentially created a new magazine. Miller retired in 1979, Flanagan and Piel in 1984, when Gerard Piel's son Jonathan became president and editor; circulation had grown fifteen-fold since 1948. In 1986, it was sold to the Holtzbrinck Publishing Group of Germany, which has owned it until the Springer-Nature merger. In the fall of 2008, Scientific American was put under the control of Holtzbrinck's Nature Publishing Group division.

Donald Miller died in December 1998, Gerard Piel in September 2004 and Dennis Flanagan in January 2005. Mariette DiChristina became editor-in-chief after John Rennie stepped down in June 2009, and stepped down herself in September 2019. In April 2020, Laura Helmuth assumed the role of editor-in-chief.

The magazine is the oldest continuously published magazine in the United States.

In 2009 the publisher notified collegiate libraries that yearly subscription prices for the magazine would increase by nearly 500% for print and 50% for online access to $1,500 yearly.

In 2013, Danielle N. Lee, a female scientist who blogged at Scientific American, was called a "whore" in an email by an editor at the science website Biology Online after refusing to write professional content without compensation. When Lee, outraged about the email, wrote a rebuttal on her Scientific American blog, the editor-in-chief of Scientific American, Mariette DiChristina, removed the post. DiChristina cited legal reasons for removing the blog. The editor at Biology Online was fired after the incident.

The controversy widened in the ensuing days. The magazine's blog editor, Bora Zivkovic, was the subject of allegations of sexual harassment by another blogger, Monica Byrne. Although the alleged incident had occurred about a year earlier, editor Mariette DiChristina informed readers that the incident had been investigated and resolved to Byrne's satisfaction. However, the incident involving Lee had prompted Byrne to reveal the identity of Zivkovic, following the latter's support of Lee. Zivkovic admitted the incident with Byrne had taken place. He apologized to Byrne, and referred to the incident as "singular", stating that his behavior was not "engaged in before or since".

Zivkovic resigned from the board of Science Online, the popular science blogging conference that he co-founded with Anton Zuiker. Following Zivkovic's admission, several female bloggers, including other bloggers for the magazine, wrote their own accounts, alleging additional incidents of sexual harassment, although none of these accounts were independently investigated. A day after these new revelations, Zivkovic resigned from his position at Scientific American.

Offices of the Scientific American have included 37 Park Row in Manhattan and the Woolworth Building in 1915 when it was just finished two years earlier in 1913. The Woolworth Building was at the time one of the first skyscrapers in the city and the tallest one in the world.
