Life

He was the son of Captain Reinhold Seehl (d. 1721), a German volunteer who worked his way through the ranks in the Swedish army.[ citation needed ] He settled in England and was naturalised as a British subject by Act of Parliament introduced in 1783 (23 Geo c. 8). [3]

Seehl occurs in a London subscription list in 1757. [4] He was one of just three people with addresses in Poplar and Blackwall to be found in Thomas Mortimer's Universal Director of 1763. There his entry reads "Seehl, Ephraim Rinhold, Copperas Merchant, Blackwall; or at the Bank Coffee-house, Threadneedlestreet." At this time he was leasing the Copperas Works in Bromley from his brother-in-law, the shipwright John Perry of Blackwall Yard. [5] [6]

Seehl traveled widely in Europe. He was a subscriber to Mineralogia Cornubiensis (1778) by William Pryce. His autograph book shows that he was almost certainly a Rosicrucian.[ citation needed ]

Seehl's will was proved 12 September 1783. [1]

Publications

Seehl worked on the compounds of sulphur. The distinction of its acids, and sulphur dioxide, was not clarified at this point. The preparation of sulphuric acid was known by the beginning of the 17th century. With Augustus Sala, Nicolas Lemery and J. C. Bernhardt, Seehl is mentioned as one of those working on methods for its production. [7] The method of making it by heating sulphur with saltpetre has been attributed to him. [8]

Seehl published An Easy Method of Procuring the Volatile Acid of Sulphur in Philosophical Transactions in 1744. [9] It referred to the preparation of sulphurous acid. [10]

<span class="mw-page-title-main">Iron(II) sulfate</span> Chemical compound

Iron(II) sulfate (British English: iron(II) sulphate) or ferrous sulfate denotes a range of salts with the formula FeSO4·xH2O. These compounds exist most commonly as the heptahydrate (x = 7) but several values for x are known. The hydrated form is used medically to treat or prevent iron deficiency, and also for industrial applications. Known since ancient times as copperas and as green vitriol (vitriol is an archaic name for sulfate), the blue-green heptahydrate (hydrate with 7 molecules of water) is the most common form of this material. All the iron(II) sulfates dissolve in water to give the same aquo complex [Fe(H2O)6]2+, which has octahedral molecular geometry and is paramagnetic. The name copperas dates from times when the copper(II) sulfate was known as blue copperas, and perhaps in analogy, iron(II) and zinc sulfate were known respectively as green and white copperas.

Johann Reinhold Forster was a German Reformed (Calvinist) pastor and naturalist of partially Scottish descent who made contributions to the early ornithology of Europe and North America. He is best known as the naturalist on James Cook's second Pacific voyage, where he was accompanied by his son Georg Forster. These expeditions promoted the career of Johann Reinhold Forster and the findings became the bedrock of colonial professionalism and helped set the stage for the future development of anthropology and ethnology. They also laid the framework for general concern about the impact that alteration of the physical environment for European economic expansion would have on exotic societies.

Karl Leonhard Reinhold was an Austrian philosopher who helped to popularise the work of Immanuel Kant in the late 18th century.

Sturm und Drang was a proto-Romantic movement in German literature and music that occurred between the late 1760s and early 1780s. Within the movement, individual subjectivity and, in particular, extremes of emotion were given free expression in reaction to the perceived constraints of rationalism imposed by the Enlightenment and associated aesthetic movements. The period is named after Friedrich Maximilian Klinger's play of the same name, which was first performed by Abel Seyler's famed theatrical company in 1777.

<i>Observations Made During a Voyage Round the World</i> Johann Reinhold Forsters 1777 account of the second voyage of James Cook

Observations Made During a Voyage Round the World is Johann Reinhold Forster's systematic account of the scientific and ethnological results of the second voyage of James Cook. Forster, a former pastor who had become a Fellow of the Royal Society after writing several papers on natural history, and his son Georg had accompanied James Cook as naturalists on board of HMS Resolution. Originally, it had been planned that Forster's account should appear together with Cook's "narrative" of the voyage, but after lengthy arguments between Forster and John Montagu, 4th Earl of Sandwich, the First Lord of the Admiralty, Georg went ahead and published his own narrative instead in 1777, A Voyage Round the World. Observations then appeared in 1778, financed by subscriptions. It was translated into several European languages, including a German translation by Georg Forster.
