By Nekud October 13, 2026 20 min read

Scientific American, the American popular-science magazine, has been continuously published since its first issue on 28 August 1845, and the magazine is the oldest continuously published periodical magazine in the United States. The magazine had, by the late nineteenth century, become the principal American popular-science publication of the industrial era, and the magazine had, by the mid-twentieth century, become the principal American popular-science publication of the post-war period. The magazine is, by the standard accounts of the founding of the magazine, the principal American popular-science publication of the modern period, and the magazine is one of the principal publications of the modern American popular-science tradition.

The magazine was founded by the inventor and painter Rufus Porter in 1845 as a four-page weekly broadsheet subtitled The Advocate of Industry and Enterprise, and the founding was, in the standard accounts of the founding of the magazine, the basis for the subsequent substantial history of the magazine of the period. The founding was, in the standard accounts of the founding of the magazine, the basis for the subsequent substantial American popular-science journalism of the modern period, and the founding had been the basis for the subsequent substantial history of the magazine of the period.

Rufus Porter and the founding

Scientific American was founded on 28 August 1845 by Rufus Porter, a New England inventor and journalist who had previously edited a number of short-lived American periodicals. Porter’s conception of the magazine was distinctive: he conceived it as a periodical of useful inventions, mechanics, and industrial chemistry, intended for the substantial American popular readership that existed in the 1840s. Porter also pioneered the magazine’s distinctive illustrated format, with substantial detailed engravings of the inventions and mechanisms described in the text. The first issue of the magazine was a substantial document, and the magazine’s early issues combined short articles on useful inventions with longer essays on the broader principles of natural philosophy. Porter sold the magazine after a few years, but the magazine continued under subsequent owners and editors through the 1840s and 1850s. The magazine’s nineteenth-century circulation grew substantially through the 1850s and 1860s, and by the 1870s the magazine was the most widely circulated scientific periodical in the United States.

The nineteenth-century heyday

The nineteenth-century heyday of Scientific American was the period when the magazine acquired its distinctive character as a publication of popular science for an educated general readership. The magazine’s coverage of the new electrical technologies — telegraphy, telephony, electric lighting — was substantial in this period, and the magazine’s coverage of the new mechanical engineering — steam engines, internal combustion engines, machine tools — was similarly substantial. The magazine’s coverage of industrial chemistry was substantial too. The magazine under its various nineteenth-century editors maintained its illustrated format, and the magazine’s engravings were a substantial part of its appeal. The magazine’s coverage of the new biology of the late nineteenth century, including Darwin’s theory of evolution and the new German experimental biology, was more modest than the magazine’s coverage of engineering and invention. The magazine by 1900 was the most widely read scientific periodical in the United States, with a circulation of around thirty thousand.

The early twentieth-century redesign

The early twentieth century brought substantial changes to Scientific American. The magazine’s long-time ownership by the Munn family, who had owned the magazine since the 1840s, came to an end in 1921 when the magazine was acquired by a new ownership group. The magazine’s editorial line shifted through the 1920s and 1930s from a focus on invention and engineering to a focus on the new biology and the new physics of the period. The magazine’s coverage of relativity, of quantum mechanics, and of the new astronomy was substantial in this period. The magazine’s coverage of biology and medicine was also substantial. The magazine’s circulation through the 1920s and 1930s continued to grow, reaching a substantial peak in the late 1940s. The editorship through this period was in the hands of several successive editors, with the most substantial being Dennis Flanagan, who took over the editorship in 1947 and ran the magazine for the next 37 years.

The Flanagan golden age

The Flanagan era of the editorship, from 1947 to 1984, is generally regarded as the golden age of Scientific American. The magazine under Flanagan developed its distinctive editorial register of substantial long-read articles by leading scientists, with the text accompanied by substantial detailed illustrations. The magazine’s contributors through this period included many of the leading American scientists of the second half of the twentieth century, including Linus Pauling, Richard Feynman, Stephen Jay Gould, and many others. The magazine’s coverage of the molecular biology revolution of the 1950s and 1960s was substantial: the magazine published articles on the structure of DNA, on the genetic code, on protein synthesis, and on the broader molecular revolution by the leading scientists of the period. The magazine’s coverage of the physics of the period was also substantial. The magazine’s circulation through the Flanagan period reached a substantial peak in the 1970s, with a circulation of around a million readers.

The 1980s-2010s transitions

The transitions of the 1980s and 1990s at Scientific American were substantial. The Flanagan era ended with Flanagan’s retirement in 1984, and the magazine’s subsequent editorship under Jonathan Piel (1984-1994) and John Rennie (1994-2009) saw substantial editorial and design restructuring of the magazine. The magazine’s coverage of the new computer sciences, of the new genetics, of the new cosmology, and of the new environmental sciences was substantial through this period. The magazine’s ownership through this period was in private hands, and the ownership of the magazine changed hands several times through the late twentieth and early twenty-first centuries. The magazine’s circulation, like that of the other major American popular-science magazines of the period, began to decline in the 2000s as readers migrated from print to online sources. The magazine’s transition to the digital era was substantial and difficult, and the magazine’s identity as a print publication was a point of tension in the editorial and ownership discussions of the period.

The Springer Nature era

The Springer Nature era of Scientific American began in 2009, when Scientific American was acquired from its previous owners by the Nature Publishing Group (subsequently absorbed into Springer Nature). The acquisition gave Scientific American a substantial new corporate parent with substantial resources in the international scientific publishing market. The magazine’s editor through this period has been Mariette DiChristina, who ran the magazine from 2009 to 2019, and the subsequent editorship has been in the hands of several individuals. The magazine’s coverage of the contemporary scientific publishing environment, including the open-access debate, the replication crisis, and the broader transformations of the scientific enterprise, has been substantial. The magazine’s international editions continue to be published in substantial numbers, with editions in many languages including Spanish, German, French, Italian, Chinese, and Japanese. The magazine’s future under Springer Nature depends on the broader evolution of the scientific publishing environment.

The future of a long-running magazine

The future of a long-running magazine like Scientific American is shaped by the broader evolution of scientific publishing, popular science reading, and the public’s relationship with science. The magazine’s history since 1845 has been a substantial one, and the magazine has outlived its founder, its founders’ families, its twentieth-century owners, and several generations of scientific publishing environment. The magazine’s contemporary challenge is that the popular-science periodical as a form has been substantially disrupted by the rise of online science writing, by the rise of podcasts and video science content, and by the broader shifts in media consumption. The magazine has adapted to each of these shifts through its history, and the magazine is likely to continue to adapt in the coming decades. The Scientific American brand is, in 2026, one of the most recognised science brands in the world, and the magazine’s continued publication under its current ownership is one of the substantial continuities of modern American scientific publishing.

Women’s coverage and the magazine’s domestic identity

The historical coverage of women’s contributions to science in Scientific American has been substantial, and the magazine’s editorial coverage of women scientists has shifted substantially over the magazine’s history. The magazine’s coverage of women scientists in the nineteenth and early twentieth centuries was relatively limited, with the magazine’s coverage of men scientists substantially exceeding its coverage of women. The magazine’s coverage of women scientists through the late twentieth century expanded substantially, and the magazine’s coverage of the contemporary situation of women in science has been substantial. The magazine’s coverage of Marie Curie in the early twentieth century, of Rosalind Franklin in the 1950s and 1960s, and of the broader women’s contributions to science through the late twentieth and early twenty-first centuries has been a substantial part of the magazine’s editorial output. The magazine’s identification of the gender gap in science as a major social problem has been substantial.

The mathematical columns

The mathematical columns of Scientific American have been one of the journal’s distinctive contributions to mathematical communication. The column “Mathematical Games”, written by Martin Gardner from 1956 to 1981, was one of the most widely read popular mathematics columns of the twentieth century, and Gardner’s coverage of recreational mathematics, of mathematical puzzles, and of the broader mathematical culture was substantial. The column was succeeded by “Mathematical Recreations”, written by Douglas Hofstadter, and subsequently by Ian Stewart. The mathematical columns of the magazine have been a substantial part of the magazine’s identity and have been read by substantial numbers of people who have gone on to careers in mathematics and in mathematically-intensive sciences. The mathematical columns are, in this sense, one of the substantial legacies of the magazine.

The 1984 transition and the Pelham era

The transition of 1984 at Scientific American, when the magazine’s editorship passed from Dennis Flanagan to Jonathan Piel, was a substantial transition. Piel ran the magazine from 1984 to 1994, and his editorship brought substantial design and editorial changes to the magazine. The magazine’s design was redesigned substantially in 1984, and the subsequent design changes through the 1980s and 1990s reshaped the magazine substantially. The magazine’s coverage of the new biology, of the new computer sciences, and of the new physics of the late twentieth century was substantial under Piel. Piel was succeeded by John Rennie, who ran the magazine from 1994 to 2009 and continued the substantial editorial coverage of contemporary science. Rennie was succeeded by Mariette DiChristina, who ran the magazine from 2009 to 2019 and was editor at the time of the Nature Publishing Group acquisition.

The replication crisis and contemporary journalism

The replication crisis affecting much of the published scientific literature of the 2010s was a substantial issue for Scientific American. The magazine’s editorial coverage of the crisis, including its publication of substantial commentary on the methodological reform of science, was substantial. The magazine’s coverage of the open-access debate, of the broader transformations in scientific publishing, and of the contemporary questions about science and society has been substantial. The magazine’s contemporary place in the science journalism landscape is substantial, and the magazine’s identity as a publication that addresses scientific questions for an educated general readership remains a substantial part of its identity. The magazine’s continuation as such in the digital era is one of the substantial continuities of American popular science writing.
