Painting by Eugène Delacroix: Liberty Leading the People (French: La Liberté guidant le peuple) commemorates the July Revolution of 1830, which toppled King Charles X of France. A woman personifying the concept and the Goddess of Liberty leads the people forward over a barricade and the bodies of the fallen, holding the flag of the French Revolution — the tricolour flag, which remains France's national flag — in one hand and brandishing a bayonetted musket with the other. The figure of Liberty is also viewed as a symbol of France and the French Republic known as Marianne. By the time Delacroix painted Liberty Leading the People, he was already the acknowledged leader of the Romantic school in French painting.
Charles Lyell's multi-volume Principles of Geology appear (between 1830 amd 1833), advancing the theory of uniformitarianism, i.e., the view that geological formations are explainable in terms of forces and conditions observable at present.
Georg Goldfuss announces that he sees "hairs" on a pterosaur fossil. This outlandish assertion will be supported by later finds.
The first edition of Birds of America, by the painter and ornithologist John James Audubon (1785-1851), appears.
On April 6, the Church of Jesus Christ of Latter-Day Saints is founded by Joseph Smith Jr. (1805-1844), in Fayette, New York. In Palmyra, New York, The Book of Mormon is published for the first time; Smith has translated it, he says, from golden tablets he found buried near Palmyra.
The first wagon trains to cross the Rocky Mountains arrived in California.

Nat Turner leads a slave rebellion in Southampton, Virginia, killing at least 57 whites. Hundreds of black slaves are killed in retaliation.
Alabama makes it illegal for enslaved or free blacks to preach.
In Boston, William Lloyd Garrison founds the abolitionist newspaper, The Liberator, signaling a dramatic shift in the antislavery movement. In the previous decades, it had centered in the South and favored a combination of compensated emancipation and colonization of freed slaves back to Africa. In the 1830s, the abolitionist movement becomes the dominant voice among antislavery advocates. Abolitionists demand the immediate end to slavery, which they consider to be a moral evil, without compensation to slaveowners.
Nat Turner, a literate slave who believes he is chosen to be the Moses of his people, instigates a slave revolt in Virginia. He and his followers kill 57 whites, but the revolt is unsuccessful and up to 200 slaves are killed. After an intense debate, the Virginia legislature narrowly rejects a bill to emancipate Virginia's slaves. The widespread fear of slave revolts, compounded by the rise of abolitionism, leads legislatures across the South to increase the harshness of their slave codes. Also, expressions of anti-slavery sentiment are suppressed throughout the South through state and private censorship.
North Carolina enacts a statute that bans teaching enslaved people to read and write.
Slave Revolt: Virginia Slave preacher Nat Turner leads a two-day uprising against whites, killing about 60. Militiamen crush the revolt then spend two months searching for Turner, who is eventually caught and hanged. Enraged Southerners impose harsher restrictions on their slaves.

Painting by Caspar David Friedrich: The Stages of Life (German: Die Lebensstufen) is an allegorical oil painting completed just five years before his death. This picture, like many of his works, forms a meditation both on his own mortality and on the transience of life. The painting is set on a sea shore and shows in the foreground an aged man with his back turned to the viewer, walking towards two adults and two children on a hilltop overlooking a harbour. The figures are echoed by five ships shown in the harbour, each at a different distance from the shore, an allegorical reference to the different stages of human life, to the end of a journey, to the closeness of death. The figures have been identified as Friedrich and his family. The aged man is the artist himself, the small boy is his young son Gustav Adolf, the young girl is his daughter Agnes Adelheid, the older girl is his daughter Emma, and the man in the top hat is his nephew Johann Heinrich.}The Stages of Life (German: Die Lebensstufen) is an allegorical oil painting of 1835 by the German Romantic landscape painter Caspar David Friedrich.

While serving as scientific officer on the HMS Beagle, Charles Darwin visits the Galapagos Islands. He observes that the many varieties of finches on the islands seem to have developed from a common ancestor found on the mainland of South America.
Adam Sedgwick names the Cambrian System, recognizing the first rich assemblage of fossils in the rock record. Roderick Murchison names the Silurian System. He believes (not entirely accurately) that the Silurian predates the fossils of land plants, and consequently any economically valuable coal seams. Murchison and Sedgwick will later develop a bitter priority dispute over these systems.
Gustave-Gaspard Coriolis's Mémoire sur les equations du mouvement relatif des sytèms de corps (Memoir on the equations of relative movement of systems of bodies) describes the Coriolis effect: the deflection of a moving body caused by Earth's rotation. The Coriolis effect is important in the study of wind. However, the claim that the Coriolis effect determines the direction water rotates when going down a drain is a myth.

Daguerreotype by Louis Daguerre: The earliest reliably dated photograph of people, taken one spring morning in 1838 from the window of the Diorama, where Daguerre lived and worked. It bears the caption huit heure du matin (8 a.m.). Though it shows the busy Boulevard du Temple, the long exposure time (about ten or twelve minutes) meant that moving traffic cannot be seen; however, the bootblack and his customer at lower left remained still long enough to be distinctly visible. The building signage at the upper left shows that the image is laterally (left-right) reversed, as were most daguerreotypes.
M. J. Schleiden and T. Schwann develop the cell theory. Schleiden notes nucleoli within nuclei.
Chemist Jöns Jakob Berzelius (1779-1848) shows that the presence of iron is what enables blood to absorb as much oxygen as it does.

Roderick Murchison and Adam Sedgwick name the Devonian System.
The English scientist Michael Faraday concludes from his work on electromagnetism that, contrary to scientific opinion of the time, the divisions between the various kinds of electricity are illusory. He also establishes that magnetism can affect rays of light, and that there is an underlying relationship between the two phenomena.
La Amistad was a 19th-century two-masted schooner, owned by a Spaniard living in Cuba. It became renowned in July 1839 for a slave revolt by Mende captives, who had been enslaved in Sierra Leone, and were being transported from Havana, Cuba to their purchasers' plantations. The African captives took control of the ship, killing some of the crew and ordering the survivors to sail the ship to Africa. The Spanish survivors secretly maneuvered the ship north, and La Amistad was captured off the coast of Long Island by the brig USS Washington. The Mende and La Amistad were interned in Connecticut while federal court proceedings were undertaken for their disposition. The owners of the ship and Spanish government claimed the slaves as property; but the US had banned the African trade and argued that the Mende were legally free. Because of issues of ownership and jurisdiction, the case gained international attention. Former president John Quincy Adams argued on behalf of the slaves when the appeal was brought before the U.S. Supreme Court, which eventually determined the Africans to be free men. The case became a symbol in the United States in the movement to abolish slavery.
Louis-Jacques-Mandé Daguerre perfects and presents the daguerreotype process as the first publicly available photographic process (which for nearly twenty years was also the one most commonly used). To make the image, a daguerreotypist would polish a sheet of silver-plated copper to a mirror finish, treat it with fumes that made its surface light sensitive, expose it in a camera for as long as was judged to be necessary, which could be as little as a few seconds for brightly sunlit subjects or much longer with less intense lighting; make the resulting latent image on it visible by fuming it with mercury vapor; remove its sensitivity to light by liquid chemical treatment, rinse and dry it, then seal the easily marred result behind glass in a protective enclosure.
Henry Fox Talbot publicly introduces the paper-based process he worked out in 1835, calling it "photogenic drawing", but it requires much longer exposures than the daguerreotype and the results are not as clear and detailed.
John Herschel introduces hyposulfite of soda (now known as sodium thiosulfate but still nicknamed "hypo") as a highly effective fixer for all silver-based processes. He also makes the first glass negative.
Sarah Anne Bright creates a series of photograms, six of which are known to still exist. These are the earliest surviving photographic images created by a woman.

The first electric clock is built by physicist Carl August Steinheil (1801-1870).
In response to the British opium trade, Lin Zexu wrote a letter to Queen Victoria, urging her to end the opium trade: We find that your country is sixty or seventy thousand li from China. Yet there are barbarian ships that strive to come here for trade for the purpose of making a great profit. The wealth of China is used to profit the barbarians. That is to say, the great profit made by barbarians is all taken from the rightful share of China. By what right do they then in return use the poisonous drug to injure the Chinese people? Even though the barbarians may not necessarily intend to do us harm, yet in coveting profit to an extreme, they have no regard for injuring others. Let us ask, where is your conscience? The letter to the Queen never reached her. Belatedly, it was delivered and published in The Times of London.
Lin Zexu was a Chinese scholar-official of the Qing dynasty best known for his role in the First Opium War of 183942. In March 1839, Lin arrived in Guangdong Province to take measures that would eliminate the opium trade. He was a formidable bureaucrat known for his competence and high moral standards, with an imperial commission from the Daoguang Emperor to halt the illegal importation of opium by the British. Upon arrival, he made changes within a matter of months. He arrested more than 1,700 Chinese opium dealers and confiscated over 70,000 opium pipes. He initially attempted to get foreign companies to forfeit their opium stores in exchange for tea, but this ultimately failed. Lin resorted to using force in the western merchants' enclave. A month and a half later, the merchants gave up nearly 1.2 million kg (2.6 million pounds) of opium. Beginning 3 June 1839, 500 workers laboured for 23 days to destroy it, mixing the opium with lime and salt and throwing it into the sea outside of Humen Town. Lin composed an elegy apologising to the gods of the sea for polluting their realm.
The First Opium War between Britain and China occurs between 1839 and 1842, triggered when Chinese officials attempt to prevent the sale of narcotics (opium) to the Chinese people by the British East India trading Company. The British respond by bringing in gunboats and shelling Chinese coastal cities.
The process of vulcanization, developed by Charles Goodyear, makes possible the commercial use of rubber.
In the early 1990's, Robert Robbins was a faculty member at Johns Hopkins, where he directed the informatics core of GDB — the human gene-mapping database of the international human genome project. To share papers with colleagues around the world, he set up a small paper-sharing section on his personal web page. This small project evolved into The Electronic Scholarly Publishing Project.
In 1995, Robbins became the VP/IT of the Fred Hutchinson Cancer Research Center in Seattle, WA. Soon after arriving in Seattle, Robbins secured funding, through the ELSI component of the US Human Genome Project, to create the original ESP.ORG web site, with the formal goal of providing free, world-wide access to the literature of classical genetics.
Although the methods of molecular biology can seem almost magical to the uninitiated, the original techniques of classical genetics are readily appreciated by one and all: cross individuals that differ in some inherited trait, collect all of the progeny, score their attributes, and propose mechanisms to explain the patterns of inheritance observed.
In reading the early works of classical genetics, one is drawn, almost inexorably, into ever more complex models, until molecular explanations begin to seem both necessary and natural. At that point, the tools for understanding genome research are at hand. Assisting readers reach this point was the original goal of The Electronic Scholarly Publishing Project.
Usage of the site grew rapidly and has remained high. Faculty began to use the site for their assigned readings. Other on-line publishers, ranging from The New York Times to Nature referenced ESP materials in their own publications. Nobel laureates (e.g., Joshua Lederberg) regularly used the site and even wrote to suggest changes and improvements.
When the site began, no journals were making their early content available in digital format. As a result, ESP was obliged to digitize classic literature before it could be made available. For many important papers — such as Mendel's original paper or the first genetic map — ESP had to produce entirely new typeset versions of the works, if they were to be available in a high-quality format.
Early support from the DOE component of the Human Genome Project was critically important for getting the ESP project on a firm foundation. Since that funding ended (nearly 20 years ago), the project has been operated as a purely volunteer effort. Anyone wishing to assist in these efforts should send an email to Robbins.
With the development of methods for adding typeset side notes to PDF files, the ESP project now plans to add annotated versions of some classical papers to its holdings. We also plan to add new reference and pedagogical material. We have already started providing regularly updated, comprehensive bibliographies to the ESP.ORG site.
