Simms, F.R.A.S.' the the base of the image, depicting a seated gentleman next to a Smith Beck & Beck, No.1 folding microscope with Varly stage, image 155mm x 208mm, in modern card mountFrederick Walter Simms (24 December 1803 – 27 February 1865) was a British civil engineer, known for his association with the Greenwich Observatory. He was the brother of William Simms (1793–1860), who, alongside his partner Edward Troughton formed the company of scientific instrument makers Troughton & Simms.Before joining the Greenwich Observatory in 1830, Simms apprenticed as a surveyor and contributed to the Trigonometrical Survey of Ireland. His tenure at the Observatory began when Thomas Glanville Taylor departed for the Directorship of the Madras Observatory. By 1835, Simms' responsibilities, as listed by John Pond, included observations with the Zenith Tube alongside John Henry Belville, occasional work with other instruments, proofreading printed observations with Henry, and overseeing the publication process of the annual volumes of Greenwich Observations. While Pond commended Simms as "very able and diligent," he also noted irregularities in chronometer rates, which eventually led to expectations of retirement.Despite being paid a modest salary supplemented by earnings from navigation lessons and surveying tasks, Simms found the financial arrangement insufficient. His dissatisfaction culminated in his resignation on 21 October 1835, shortly after the arrival of the new Astronomer Royal, Airy. Airy, in his autobiography, remarked that Simms had hoped for the position of First Assistant, a role for which Airy deemed him unfit.Following his departure from the Observatory, Simms pursued a new career path as a railway surveyor and engineer. In 1836, Simms commenced his role as a resident engineer with the South Eastern Railway Company, embarking on various significant projects, including the construction of the Bletchingley and Saltwood tunnels. He authored several books on surveying and tunnelling and produced the 1838 Map of The Parish of Greenwich in the County of Kent for the Tithe Commissioners.In 1846, the East India Company, seeking to expand railway infrastructure in their territories, approached Simms to serve as their consulting engineer in India. Despite grappling with health issues exacerbated by the climate, Simms briefly sojourned in Mauritius before resuming his duties. Among his responsibilities was overseeing the comprehensive survey and mapping of Calcutta, primarily conducted by local assistants.Upon concluding his tenure with the East India Company, Simms returned to England in 1851, his health notably deteriorated due to the harsh conditions in India. He subsequently retired from active professional life.
Glass Bottle Containing Soundings from the H.M.S. Challenger Expedition, 1876,Glass Bottle, hand blown with pontil mark with label that reads 'Washigs of Soundings No.337 Date 9.March.1876 Lat37 47 5 Long 30 20 W Depth 1715 fthm', bottle with original contents.Provenance originally from a collection of microscope preparation equipment belonging to Charles ElcockCharles Elcock (1834-1910) was a well known figure in the world of microscopy, particularly known for his expertise in creating microscope slides featuring foraminifera, a group of amoeboid protists characterized by their intricate shell structures. Born in Pontefract, Yorkshire, England, on August 18, 1834, Elcock was the second son of Charles and Mary Ann Elcock. The Elcock family were Quakers, a religious background that profoundly influenced Charles throughout his life, as reflected in his writings and humanitarian efforts during the Franco-Prussian War. Elcock's early career was varied, encompassing teaching and publishing, but it was his later work in microscopy for which he is remembered.Early Life and Career.Elcock's early years were marked by a strong education and a diverse set of experiences. After the death of his father in 1837, his mother took up teaching to support the family. Elcock attended the Friends' School at Rawdon, which was a formative experience given the Quaker values emphasized there. His early professional life included roles as a teacher and printer, and he maintained a close association with the Quaker community throughout. By the 1860s, Elcock was involved in publishing religious texts, which eventually led to his work in London and Gloucester, where he likely developed his interest in microscopy through his connection with Alfred William Bennett, a prominent member of the Royal Microscopical Society.Microscopy and Foraminifera.Charles Elcock's most significant contribution to science was his work with microscopy, particularly in mounting foraminifera on microscope slides. Foraminifera are microscopic marine organisms that produce a shell, often referred to as a "test," which can be quite intricate and beautiful. Elcock's slides were celebrated not just for their scientific utility but also for their aesthetic appeal. His work involved arranging these tiny shells meticulously on slides, often organizing them by species and orientation, which made his slides valuable for both scientific study and as objects of beauty.Elcock's expertise in preparing these slides was widely recognized. He became a member of the Belfast Naturalists' Field Club shortly after moving to Ireland, where his skills in mounting foraminifera were lauded. In 1879, his work won a prize from the club for its artistic skill and superior finish. His techniques and methods were innovative, and he shared his knowledge through articles, most notably in the Journal of the Postal Microscopical Society, where he also advertised his slides.Legacy and Impact.Elcock's slides were distributed through well-known retailers in London, Manchester, and Bath, and they were highly regarded by contemporary scientists and hobbyists alike. Reviews of his work praised the meticulous attention to detail and the scientific value of the slides. His contributions to microscopy, particularly in the study of foraminifera, have left a lasting legacy in the field. While much of his life was also dedicated to religious writing and humanitarian efforts, it is his work in microscopy that has cemented his place in the history of science. A large part of his original equipment and the slides he produced is held at the Whipple Museum of Science in Cambridge: https://www.whipplemuseum.cam.ac.uk/explore-whipple-collections/microscopes/foraminifera-slides-and-working-tools-microscope-slide-makerChallenger Expedition: Revolutionizing Oceanography through Deep-Sea SoundingsThe Challenger Expedition (1872-1876), a pioneering oceanographic endeavor, marked a turning point in our understanding of marine sciences. This British voyage, named after the HMS Challenger, was the first dedicated scientific exploration to systematically study ocean basins, marine life, and geology. Among its most critical contributions were the extensive soundings, temperature recordings, and water samples taken during the expedition, which have had a lasting impact on oceanography.Deep-sea soundings, the process of measuring the depth of the ocean, were among the most revolutionary aspects of the Challenger Expedition. Utilizing newly developed sounding equipment, the expedition made nearly 500 soundings across the world’s oceans. These measurements were pivotal, not only in mapping the seabed but also in discovering the global patterns of oceanic trenches, underwater mountains, and plains.Prior to the Challenger Expedition, the depths of the oceans were largely unknown. The sounding techniques employed involved lowering weighted lines, known as sounding lines, into the ocean until they reached the seabed. The depths recorded by Challenger revealed for the first time the complex topography of the ocean floor. One of the most significant findings was the Challenger Deep in the Mariana Trench, recorded as the deepest part of the world's oceans.The data collected on these soundings provided foundational knowledge that spurred further scientific inquiry. For instance, the temperature profiles of ocean waters at different depths, also recorded during these soundings, helped scientists to begin understanding thermocline and its role in oceanic circulation patterns.The implications of these findings were vast. They challenged previous notions of a lifeless deep sea by providing evidence of life at all depths, and the samples of sediment helped develop the fields of marine geology and paleontology. This wealth of data collected by the Challenger laid the groundwork for modern oceanography and prompted the establishment of permanent oceanographic institutions.The Challenger Expedition was instrumental in transforming oceanography from a field cluttered with myths and speculations to a serious scientific discipline. Its soundings opened up new realms in the understanding of oceanic depths and laid down the benchmarks for future explorations, forever altering our relationship with the oceans. The expedition not only charted unknown waters but also set the course for future marine scientific endeavors, proving its legacy in the history of science.
