Mezzotint is a printmaking process of the intaglio family, technically a drypoint method. It was the first tonal method to be used, enabling half-tones to be produced without using line- or dot-based techniques like hatching, cross-hatching or stipple. Mezzotint achieves tonality by roughening the plate with thousands of little dots made by a metal tool with small teeth, called a "rocker." In printing, the tiny pits in the plate hold the ink when the face of the plate is wiped clean. A high level of quality and richness in the print can be achieved.

The mezzotint printmaking method was invented by the German amateur artist Ludwig von Siegen (1609–c 1680). His earliest mezzotint print dates to 1642 and is a portrait of Amelia Elizabeth, Landgravine of Hesse-Kassel (or Hesse-Cassel) (right). This was made by working from light to dark. The rocker seems to have been invented by Prince Rupert of the Rhine, a famous cavalry commander in the English Civil War, who was the next to use the process, and took it to England. Sir Peter Lely saw the potential for using it to publicise his portraits, and encouraged a number of Dutch printmakers to come to England. The process was especially widely used in England from the mid-eighteenth century, to reproduce portraits and other paintings. Since the mid-nineteenth century it has been relatively little used. Robert Kipniss and Peter Ilsted are two notable 20th-century exponents of the technique; M. C. Escher also made seven mezzotints.

Ryan Joseph O'Malley (born April 9, 1980) is a former Major League Baseball pitcher. He played for the Chicago Cubs in 2006.

O'Malley made his major league debut for the Cubs on August 16, 2006, against the Houston Astros. He pitched eight innings, giving up five hits, six walks, two strikeouts and no runs in a 1-0 win. In his next start, he pitched four and two-thirds innings before leaving with a strained left elbow. He was activated from the disabled list on September 8, 2006.

On January 9, 2007, the Cubs announced that O'Malley would be among 11 non-roster players invited to spring training camp in Mesa, Arizona.

In February 2008, O'Malley was signed by the Schaumburg Flyers of the independent Northern League, but before appearing in a game for them, he left to sign a minor league contract with the Chicago White Sox. He became a free agent at the end of the season.

On December 2, 2009, O'Malley was named the pitching coach for the Arizona League Rangers.

Montague Rhodes James, OM, MA, (1 August 1862 – 12 June 1936), who used the publication name M. R. James, was an English mediaeval scholar and provost of King's College, Cambridge (1905–1918), and of Eton College (1918–1936). He is best remembered for his ghost stories, which are regarded as among the best in the genre. James redefined the ghost story for the new century by abandoning many of the formal Gothic clichés of his predecessors and using more realistic contemporary settings. However, James's protagonists and plots tend to reflect his own antiquarian interests. Accordingly, he is known as the originator of the "antiquarian ghost story".

James was born in Goodnestone Parsonage in Kent, England, although his parents had associations with Aldeburgh in Suffolk. From the age of three (1865) until 1909 his home, if not always his residence, was at the Rectory in Great Livermere, Suffolk. This had also been the childhood home of another eminent Suffolk antiquary, "Honest Tom" Martin (1696–1771) "of Palgrave." Several of his ghost stories are set in Suffolk, including "'Oh, Whistle, and I'll Come to You, My Lad'" (Felixstowe), "A Warning to the Curious" (Aldeburgh), "Rats" and "A Vignette" (Great Livermere). He lived for many years, first as an undergraduate, then as a don and provost, at King's College, Cambridge. The university provides settings for several of his tales. Apart from mediaeval subjects, James studied the classics and appeared very successfully in a staging of Aristophanes' play The Birds, with music by Hubert Parry. His ability as an actor was also apparent when he read his new ghost stories to friends at Christmas time.^{[citation needed]}

David Bone Nightingale Jack (3 April 1899 – 10 September 1958) was an English footballer, the first player ever to score at Wembley, and the first footballer in the world to be transferred for more than £10,000. His father, Bob Jack, was also a footballer, as were his brothers Rollo and Donald.

An inside forward, born in Bolton, Lancashire, Jack started his career with his father's club, Plymouth Argyle in 1919. There he scored 15 goals in 48 appearances in all competitions. In 1920 he returned to the town of his birth, moving to Bolton Wanderers for £3,500. He spent eight seasons with the Trotters, forming a formidable partnership with Joe Smith, and between them they scored over 300 goals. While at Bolton, he made history by being the first person to score a goal at Wembley Stadium, in the 1923 FA Cup Final; Bolton won 2–0 and Jack earned his first medal.

A year later, he won his first England cap, in a 1–2 defeat against Wales on 3 March 1924. In eight years he played eight times for his country and scored three times. He continued to have success with Bolton, winning the FA Cup again in 1925–26, scoring the only goal in a 1–0 win over Manchester City. He was the club's top scorer for five of the eight seasons he was there, scoring 144 goals in 295 league matches.
