Holtzapffel
The Holtzapffel dynasty of tool and lathe makers was founded in Long Acre, London by a Strasbourg-born turner, Jean-Jacques Holtzapffel, in 1794. The firm specialized in lathes for ornamental turning but also made a name for its high-quality edge and boring tools. Background Moving to London from Alsace in 1792, Jean-Jacques worked initially in the workshop of the scientific-instrument maker Jesse Ramsden, anglicizing his name to John Jacob Holtzapffel. In 1794 he set up a tool-making partnership in Long Acre with Francis Rousset, trading under the name of John Holtzapffel. From 1804 he was in partnership with the Mannheim-born Johann Georg Deyerlein until the latter's death in 1826, trading under the name Holtzapffel & Deyerlein. Operations Holtzapffel sold his first lathe in June 1795, for £25-4s-10d, an enormous price at the time. All of Holtzapffel's lathes were numbered and by the time he died in 1835, about 1,600 had been sold. The business was located at 64 Charing Cros ...

Ornamental Turning
Ornamental turning is a type of turning, a craft that involves cutting of a work mounted in a lathe. The work can be made of any material that is suitable for being cut in this way, such as wood, bone, ivory or metal. Plain turning is work executed on a lathe where a transverse section through any part of the work comprises a plain circle. Ornamental turning, also called Complex turning, is executed on a lathe with attachments which convert that plain circular section to variants of outline; these range from a simple series of cuts taken at intervals around the work (so producing grooves or bumps on the surface) to non-circular movements whereby the whole of the circular shape is removed to give a completely different form. Such shapes are achieved by various means, the principal ones being: * Cutting with a fixed or revolving cutter while the work is rotated on a non-radial path, e.g.- eccentrically, elliptically, epicyclically or, following a path determined by a template or recipr ...

Francis Ronalds
Sir Francis Ronalds FRS (21 February 17888 August 1873) was an English scientist and inventor, and arguably the first electrical engineer. He was knighted for creating the first working electric telegraph over a substantial distance. In 1816 he laid an eight-mile length of iron wire between wooden frames in his mother's garden and sent pulses using electrostatic generators. Upbringing and family Born to Francis Ronalds and Jane (née Field), wholesale cheesemongers, at their business premises in Upper Thames Street, London, he attended Unitarian minister Eliezer Cogan's school before being apprenticed to his father at the age of 14 through the Drapers' Company. He ran the large business for some years. The family later resided in Canonbury Place and Highbury Terrace, both in Islington, at Kelmscott House in Hammersmith, Queen Square in Bloomsbury, at Croydon, and on Chiswick Lane. Several of Ronalds' eleven brothers and sisters also led noteworthy lives. His younges ...

Lathe
A lathe () is a machine tool that rotates a workpiece about an axis of rotation to perform various operations such as cutting, sanding, knurling, drilling, deformation, facing, and turning, with tools that are applied to the workpiece to create an object with symmetry about that axis. Lathes are used in woodturning, metalworking, metal spinning, thermal spraying, parts reclamation, and glass-working. Lathes can be used to shape pottery, the best-known design being the Potter's wheel. Most suitably equipped metalworking lathes can also be used to produce most solids of revolution, plane surfaces and screw threads or helices. Ornamental lathes can produce three-dimensional solids of incredible complexity. The workpiece is usually held in place by either one or two ''centers'', at least one of which can typically be moved horizontally to accommodate varying workpiece lengths. Other work-holding methods include clamping the work about the axis of rotation using a chuck or col ...

Their Craftsmanship From The Earliest Times To The Twentieth Century
In Modern English, ''they'' is a third-person pronoun relating to a grammatical subject. Morphology In Standard Modern English, ''they'' has five distinct word forms: * ''they'': the nominative (subjective) form * ''them'': the accusative (objective, called the ' oblique'.) and a non-standard determinative form. * ''their:'' the dependent genitive (possessive) form * ''theirs'': independent genitive form * ''themselves'': prototypical reflexive form *''themself'': derivative reflexive form (nonstandard; now chiefly used instead of "himself or herself" as a reflexive epicenity for ''they'' in pronominal reference to a singular referent) History Old English had a single third-person pronoun '' hē'', which had both singular and plural forms, and ''they'' wasn't among them. In or about the start of the 13th century, ''they'' was imported from a Scandinavian source ( Old Norse ''þeir'', Old Danish, Old Swedish ''þer'', ''þair''), where it was a masculine plura ...

In the Books of Samuel, he is described as a young shepherd and harpist who gains fame by slaying Goliath, a champion of the Philistines, in southern Canaan.
