Eversharp
Eversharp is an American brand of writing implements founded by Charles Rood Keeran in 1913 and marketed by Keeran & Co., based in Chicago. Keeran commercialised ''Eversharp'' mechanical pencils (manufactured by two companies, Heath and Wahl), then expanding to fountain pens when the company was acquired by the Wahl Adding Machine Co. in 1916 and it was named "Wahl-Eversharp". The company continued until 1957 when it was acquired by Parker Pen, which continued to use the ''Eversharp'' brand for a time. Keeran is considered a pioneer maker of mechanical pencils,Charles Keeran, a Mechanical Pencil Pioneer on University of Nebraska-Lincoln as the inventor of the first successful one.

Charles Rood Keeran
Charles Rood Keeran (April 16, 1883 - June 9, 1948) was an Illinois inventor and businessman. Biography He was born on April 16, 1883, on a farm near Bloomington, Illinois. Having an inventive father, William Lee Keeran, C.R. Keeran grew up with a creative spirit. After achieving a master's degree in engineering, he soon began patenting his ideas (circa 1906) which continued throughout his lifetime: Keeran's 2-piece vacuum seal for Mason jars, which became the standard for home-canning, was immediately popular. However, he sold off his company, White Crown Fruit Jar, in order to finance his favorite invention: the Eversharp mechanical pencil. Around 1914, Keeran invented the basic mechanism for the Eversharp, thought up the "Eversharp" trademark (inspired by the Winchester Rifle logo), and set up a company to make and sell Eversharp pencils. He relocated to Evanston, Illinois, and entered into a business alliance with the Wahl Adding Machine Company in Chicago. Wahl offic ...

Mechanical Pencil
A mechanical pencil, also clutch pencil, is a pencil with a replaceable and mechanically extendable solid pigment core called a "lead" . The lead, often made of graphite, is not bonded to the outer casing, and can be mechanically extended as its point is worn away as it is being used. Other names include: microtip pencil, automatic pencil, drafting pencil, technical pencil, click pencil (generally refers to a specific brand), pump pencil, leadholder, Pacer (Australian English, ca. the 1980s), propelling pencil (British and Australian English, often refers to higher-end mechanical pencils), pen pencil (Indian English), and lead pencil (Bangladeshi and American English). Mechanical pencils are used to provide lines of constant width, without need of sharpening, for tasks such as technical drawing as well as for clean looking writing. They are also used for fine-art drawing. Since they do not have to be sharpened, they are also popular with students. Mechanical pencils were first ...

Fountain Pen
A fountain pen is a writing instrument which uses a metal nib to apply a water-based ink to paper. It is distinguished from earlier dip pens by using an internal reservoir to hold ink, eliminating the need to repeatedly dip the pen in an inkwell during use. The pen draws ink from the reservoir through a feed to the nib and deposits the ink on paper via a combination of gravity and capillary action. Filling the reservoir with ink may be achieved manually, via the use of an eyedropper or syringe, or via an internal filling mechanism which creates suction (for example, through a piston mechanism) or a vacuum to transfer ink directly through the nib into the reservoir. Some pens employ removable reservoirs in the form of pre-filled ink cartridges. History Early prototypes of reservoir pens According to Qadi al-Nu'man al-Tamimi (d. 974) in his ''Kitab al-Majalis wa 'l-musayarat'', the Fatimid caliph Al-Mu'izz li-Din Allah in Arab Egypt demanded a pen that would not stain his ha ...

Privately Held Company
A privately held company (or simply a private company) is a company whose shares and related rights or obligations are not offered for public subscription or publicly negotiated in the respective listed markets, but rather the company's stock is offered, owned, traded, exchanged privately, or over-the-counter. In the case of a closed corporation, there are a relatively small number of shareholders or company members. Related terms are closely-held corporation, unquoted company, and unlisted company. Though less visible than their publicly traded counterparts, private companies have major importance in the world's economy. In 2008, the 441 largest private companies in the United States accounted for ($1.8 trillion) in revenues and employed 6.2 million people, according to ''Forbes''. In 2005, using a substantially smaller pool size (22.7%) for comparison, the 339 companies on ''Forbes'' survey of closely held U.S. businesses sold a trillion dollars' worth of goods and service ...

Wanamaker's
John Wanamaker Department Store was one of the first department stores in the United States. Founded by John Wanamaker in Philadelphia, it was influential in the development of the retail industry including as the first store to use price tags. At its zenith in the early 20th century, Wanamaker's also had a store in New York City at Broadway and Ninth Street. Both employed extremely large staffs. By the end of the 20th century, there were 16 Wanamaker's outlets, but after years of change the chain was bought by Albert Taubman, and added to his previous purchase of Woodward & Lothrop, the Washington, D.C., department store. In 1994, Woodies, as it was known, filed for bankruptcy. The assets of Woodies were purchased by the May Company Department Stores and JCPenney. In 1995, Wanamaker's transitioned to Hecht's, one of the May Company brands. In 2006, Macy's Center City became the occupant of the former Philadelphia Wanamaker's Department Store, which is now a National Historic ...

Manufacturing Companies Based In Chicago
Manufacturing is the creation or production of goods with the help of equipment, labor, machines, tools, and chemical or biological processing or formulation. It is the essence of secondary sector of the economy. The term may refer to a range of human activity, from handicraft to high-tech, but it is most commonly applied to industrial design, in which raw materials from the primary sector are transformed into finished goods on a large scale. Such goods may be sold to other manufacturers for the production of other more complex products (such as aircraft, household appliances, furniture, sports equipment or automobiles), or distributed via the tertiary industry to end users and consumers (usually through wholesalers, who in turn sell to retailers, who then sell them to individual customers). Manufacturing engineering is the field of engineering that designs and optimizes the manufacturing process, or the steps through which raw materials are transformed into a final produ ...

Pen Manufacturers
A pen is a common writing instrument that applies ink to a surface, usually paper, for writing or drawing. Early pens such as reed pens, quill pens, dip pens and ruling pens held a small amount of ink on a nib or in a small void or cavity which had to be periodically recharged by dipping the tip of the pen into an inkwell. Today, such pens find only a small number of specialized uses, such as in illustration and calligraphy. Reed pens, quill pens and dip pens, which were used for writing, have been replaced by ballpoint pens, rollerball pens, fountain pens and felt or ceramic tip pens. Ruling pens, which were used for technical drawing and cartography, have been replaced by technical pens such as the Rapidograph. All of these modern pens contain internal ink reservoirs, such that they do not need to be dipped in ink while writing. Types Modern Pens commonly used today can be categorized based on the mechanism of the writing tip and the type of ink: * A ballpoint pen dis ...

Pencil Brands
A pencil () is a writing or drawing implement with a solid pigment core in a protective casing that reduces the risk of core breakage, and keeps it from marking the user's hand. Pencils create marks by physical abrasion, leaving a trail of solid core material that adheres to a sheet of paper or other surface. They are distinct from pens, which dispense liquid or gel ink onto the marked surface. Most pencil cores are made of graphite powder mixed with a clay binder. Graphite pencils (traditionally known as "lead pencils") produce grey or black marks that are easily erased, but otherwise resistant to moisture, most chemicals, ultraviolet radiation and natural aging. Other types of pencil cores, such as those of charcoal, are mainly used for drawing and sketching. Coloured pencils are sometimes used by teachers or editors to correct submitted texts, but are typically regarded as art supplies, especially those with cores made from wax-based binders that tend to smear when ...

Subsidiary
A subsidiary, subsidiary company or daughter company is a company owned or controlled by another company, which is called the parent company or holding company. Two or more subsidiaries that either belong to the same parent company or having a same management being substantially controlled by same entity/group are called sister companies. The subsidiary can be a company (usually with limited liability) and may be a government- or state-owned enterprise. They are a common feature of modern business life, and most multinational corporations organize their operations in this way. Examples of holding companies are Berkshire Hathaway, Jefferies Financial Group, The Walt Disney Company, Warner Bros. Discovery, or Citigroup; as well as more focused companies such as IBM, Xerox, and Microsoft. These, and others, organize their businesses into national and functional subsidiaries, often with multiple levels of subsidiaries. Details Subsidiaries are separate, distinct legal ...
