August 30th in stamps Mary Shelley, Christopher Polhem

Here are some events that happened on August 30th. It could be an event or a person that died or was born on that day

1751 Died: Christopher Polhem, Swedish physicist and engineer (b. 1661)

Christopher Polhammar (18 December 1661 – 30 August 1751) better known as Christopher Polhem, which he took after his ennoblement in 1716, was a Swedish scientist, inventor and industrialist. He made significant contributions to the economic and industrial development of Sweden, particularly mining. He was ennobled by King Charles XII of Sweden for his contributions to Swedish technological development.

Notable accomplishments
  • Founded Stjärnsunds manufakturverk in södra Dalarna during 1700.
  • Reinvented the Cardan joint under the name of "Polhem knot" (Swedish: Polhemknut) independently of Gerolamo Cardano, the pioneer inventor.
  • Organized machinery into a "mechanical alphabet" and provided examples of such. Of 80 models carved in wood, 32 are still in the collections of the National Museum of Science and Technology (Swedish:Tekniska Museet) in Stockholm. Another 13 models of the "mechanical alphabet" are to be found in the Falun Mining Museum, Sweden.

1797 Born: Mary Shelley, English novelist and playwright (d. 1851)

Mary Wollstonecraft Shelley (30 August 1797 – 1 February 1851) was an English novelist who wrote the Gothic novel Frankenstein; or, The Modern Prometheus (1818). She also edited and promoted the works of her husband, the Romantic poet and philosopher Percy Bysshe Shelley. Her father was the political philosopher William Godwin and her mother was the philosopher and feminist Mary Wollstonecraft.

Shelley's mother died less than a month after giving birth to her. She was raised by her father who provided her with a rich if informal education, encouraging her to adhere to his own anarchist political theories. When she was four, her father married a neighbour with whom Shelley came to have a troubled relationship. 

In 1814, Shelley began a romance with one of her father's political followers, Percy Bysshe Shelley, who was already married. Together with her stepsister, Claire Clairmont, she and Percy left for France and travelled through Europe. Upon their return to England, Shelley was pregnant with Percy's child. Over the next two years, she and Percy faced ostracism, constant debt and the death of their prematurely born daughter. They married in late 1816, after the suicide of Percy Shelley's first wife, Harriet.

In 1816, the couple famously spent a summer with Lord Byron, John William Polidori and Claire Clairmont near Geneva, Switzerland, where Shelley conceived the idea for her novel Frankenstein. The Shelleys left Britain in 1818 for Italy, where their second and third children died before Shelley gave birth to her last and only surviving child, Percy Florence Shelley. In 1822, her husband drowned when his sailing boat sank during a storm near Viareggio. A year later, Shelley returned to England and from then on devoted herself to the upbringing of her son and a career as a professional author. The last decade of her life was dogged by illness, most likely caused by the brain tumour which killed her at age 53.

Until the 1970s, Shelley was known mainly for her efforts to publish her husband's works and for her novel Frankenstein, which remains widely read and has inspired many theatrical and film adaptations. Recent scholarship has yielded a more comprehensive view of Shelley's achievements. Scholars have shown increasing interest in her literary output, particularly in her novels, which include the historical novels Valperga (1823) and Perkin Warbeck (1830), the apocalyptic novel The Last Man (1826) and her final two novels, Lodore (1835) and Falkner (1837). Studies of her lesser-known works, such as the travel book Rambles in Germany and Italy (1844) and the biographical articles for Dionysius Lardner's Cabinet Cyclopaedia (1829–1846), support the growing view that Shelley remained a political radical throughout her life. Shelley's works often argue that cooperation and sympathy, particularly as practised by women in the family, were the ways to reform civil society. This view was a direct challenge to the individualistic Romantic ethos promoted by Percy Shelley and the Enlightenment political theories articulated by her father, William Godwin.
