The Science Museum in London has found a far more interesting angle. [Becoming America: How Science Shaped a Nation](https://www.sciencemuseum.org.uk/see-and-do/becoming-america?ref=unknowndivide.com), supported by Griffin Catalyst, opens on October 23 and asks a sharper question: what did maps, instruments, crops and canoes have to do with the birth of the United States? The answer, judging by the object list, is almost everything. ## Four decades, one hundred objects The free, ticketed exhibition charts the four decades from the 1760s, when Britain took territorial control from France, through independence to the first US presidency in the 1790s. More than a hundred objects are on show, and the museum created the exhibition with the support of the [Library of Congress](https://www.loc.gov/?ref=unknowndivide.com). Lenders include [Mount Vernon](https://www.mountvernon.org/?ref=unknowndivide.com), the American Philosophical Society, the National Trust, the British Museum, the [Royal Collection Trust](https://www.rct.uk/?ref=unknowndivide.com) and The National Archives. ## The headline pieces The finale is a rare surviving Dunlap print of the Declaration of Independence from 1776, the official printed copy that carries the printer's name, John Dunlap. The museum notes it is only slightly longer than a sheet of A4 paper. Nearby sits Benjamin Franklin's chart of the Atlantic Gulf Stream, made with his whaler cousin Timothy Folger after Franklin noticed that letters took longer to cross from Britain to North America than the other way. They became the first to name and record the current. Then there is the bald eagle. Mark Catesby's watercolour, owned by King George III, shows the bird plunging toward a fish with its wings stretched across the whole sheet. It comes from what is considered the first published book to survey American flora and fauna, printed between 1729 and 1747, a book that also sat in George Washington's library. The eagle became the national emblem in 1782. ## Kings, presidents and farmers One of the smartest threads pairs George III with Washington as two powerful men who were both obsessed with science and technology. Documents show how each brought crop rotation innovations to his farms at Windsor and Mount Vernon. An ornate microscope designed specially for the king is on display, alongside Charles Willson Peale's sprawling painting Exhumation of the Mastodon, which depicts the excavation of the world's first fully articulated prehistoric skeleton. ## Knowledge beyond the founders This is not just a story about famous men. The exhibition gives real space to scientific knowledge developed by people of African descent and by Indigenous nations, with a focus on the Haudenosaunee Confederacy. A ten foot dugout canoe, commissioned specially for the show and made using traditional Indigenous American methods, anchors that section. Visitors can also see the popular almanac written by Benjamin Banneker, a freeborn astronomer, mathematician and surveyor of African descent who worked on the new capital, Washington DC. A surveyor's compass believed to have been used to define the Mason-Dixon Line rounds out a section on how maps became political. ## Plan your visit Becoming America runs from October 23, 2026 to April 25, 2027 in Special Exhibition Gallery 2 on Level 2\. Entry is free but ticketed, and the museum recommends it for ages 11 and up. It also flags that some historical material uses outdated language and imagery now considered racist. The full background is in the museum's [announcement](https://www.sciencemuseum.org.uk/about-us/press-office/becoming-america-how-science-shaped-nation-supported-griffin-catalyst-open?ref=unknowndivide.com). ## Our call This one is Surfacing. Anniversary shows usually tell you what you already know. This one swaps the speeches for instruments, canoes and a Gulf Stream map, and that makes it the most surprising way to mark 1776 we have seen. If you are in London this winter, book it.
