Rufus Porter distributed the first issue of his Scientific American with a prospectus touting the periodical as being for “those who delight in the development of those beauties of Nature, which consists in the laws of Mechanics, Chemistry, and other branches of Natural Philosophy.” He promised a paper that would instruct while it amused its reader. An eccentric character, Porter was an avid inventor who viewed scientific knowledge as a way of increasing one’s practical knowledge, and, subsequently, one’s social class. Scientific American published its first weekly issue on August 28, 1845, (the magazine went monthly in 1921) and established itself as the “advocate of industry and enterprise.”

Over the past 165 years of continuous publication, Scientific American has maintained its commitment to bringing the delights of scientific knowledge to its readers, keeping them informed about cutting-edge innovations and technologies.

It’s Time to Stand Up for Science

If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in that two-century history.

I’ve been a Scientific American subscriber since I was 12 years old, and it helped shape the way I look at the world. SciAm always educates and delights me, and inspires a sense of awe for our vast, beautiful universe. I hope it does that for you, too.

If you subscribe to Scientific American, you help ensure that our coverage is centered on meaningful research and discovery; that we have the resources to report on the decisions that threaten labs across the U.S.; and that we support both budding and working scientists at a time when the value of science itself too often goes unrecognized.

In return, you get essential news, captivating podcasts, brilliant infographics, can't-miss newsletters, must-watch videos, challenging games, and the science world's best writing and reporting. You can even gift someone a subscription.

There has never been a more important time for us to stand up and show why science matters. I hope you’ll support us in that mission.

Thank you,

David M. Ewalt, Editor in Chief, Scientific American
