# Art Fletcher

Arthur Fletcher (January 5, 1885 – February 6, 1950) was an American shortstop, manager and coach in Major League Baseball. Fletcher was associated with two New York City baseball dynasties: the Giants of John McGraw as a player; and the Yankees of Miller Huggins and Joe McCarthy as a coach.

## Career

Born in Collinsville, Illinois, he batted and threw right-handed, stood 5 feet 10 inches (1.78 m) tall and weighed 170 pounds (77 kg).
Fletcher came to the Giants in 1909 after only one season of minor league experience, and became the club's regular shortstop two years later. He played in four World Series while performing for McGraw (1911, 1912, 1913 and 1917). Traded to the Philadelphia Phillies in the midst of the 1920 season, he retired after the 1922 campaign with 1,534 hits, 32 home runs, 676 RBI and a .277 batting average. Fletcher is the Giants' career leader in being hit by pitches (132) and ranks 29th on the MLB career list (141) for the same statistic.
In 1923 he replaced Kaiser Wilhelm as manager of the seventh-place Phillies and led the club through four losing seasons, bookended by last-place finishes in 1923 and 1926. In October 1926, he was replaced by Stuffy McInnis.
Fletcher then began a 19-year tenure (1927–1945) as a coach for the Yankees, where, beginning with the legendary 1927 team, he would participate on ten American League pennant winners and nine World Series champions. On a tragic note, he served as the acting manager of Yankees for the last 11 games of the 1929 season when Huggins, 50, was fatally stricken with erysipelas and pyaemia. Fletcher won six of those 11 games, to compile a career major league managing record of 237–383 (.382).

# Orval Overall

Orval Overall (February 2, 1881 – July 14, 1947) was an American pitcher in Major League Baseball. He was a member of the Chicago Cubs dynasty of the early 1900s, making eight appearances for the Cubs in the World Series, including five as the starting pitcher (winning three with a tie and a loss).

## Biography

Overall was born in Farmersville, California. He attended the University of California, Berkeley, where he was a member of Sigma Nu, serving as director of new member (“pledge”) education, as well as captain of the football team. He was named an All-American in football.
Overall started his professional baseball career in 1904. With the Pacific Coast League's Tacoma Tigers, he pitched 510.2 innings, going 32–25 with a 2.78 earned run average. He was drafted by the Cincinnati Reds in September. In 1905, his rookie season, he was the ace of the Reds pitching staff and won 18 games. He struggled early in 1906, though, and was traded to the Chicago Cubs. In 18 games for Chicago, Overall went 12–3 with a 1.88 ERA. The 1906 Cubs set a major league record for wins in a season and won the National League pennant.
Overall pitched even better in 1907. He went 23–7 with eight shutouts and a 1.68 ERA. He also won a game in the 1907 World Series, and the Cubs won their first title. In 1908, Overall "slumped" to just 15 wins but also won twice in the 1908 World Series as Chicago repeated as champions. In that Series, Overall set a Cubs record for most strikeouts in a World Series game by a single pitcher (10), which still stands. In the series-clinching game, he shut out the Detroit Tigers on three hits. In the first inning of that game, he became the only pitcher to strike out four hitters in one inning in a World Series game, and the last to do it in a playoff game until 2013. In 1909, he won 20 games and set a career-low in ERA (1.42). He also led the NL in strikeouts, with 205.
Overall retired after the 1910 season. He made a brief comeback in 1913. In total, he played seven years in the major leagues, compiling a record of 108–71 with a 2.23 lifetime ERA. He was the vice-president and manager of a bank after his baseball career ended.
Overall died at the age of 66 in Fresno, California, and was buried at the Inglewood Park Cemetery in Inglewood, California.
# Achurch

Achurch (formerly Asenciran sometimes referred to as Thorpe Achurch) is a village in the civil parish of Thorpe Achurch, in North Northamptonshire, England. Situated on a small rise above the River Nene, 5 miles South of the market town of Oundle, the population of the civil parish of Thorpe Achurch at the 2011 census was 421.
The parish includes the Grade I listed property Lilford Hall and the Grade II* listed Church of St. John the Baptist, an early and late 13th-century Anglican church restored and enlarged by architect William Slater in 1862.

## History

The villages name means 'Asa's church' or 'Asi's church'.
Settled successively since the Iron Age the village was named after the site of the nearby church as ’Aas-kirk’, meaning Church by the Water. Subsequently named Asechirce in the Domesday Book of 1086 with land held mainly by Ascelin de Waterville, a Norman knight after whom the adjoining village of Thorpe Waterville is named. Ownership of the land passed through the Dukes of Exeter in the 14th century with Henry VII granting them to his mother Lady Margaret Beaufort. On her death the two manors of Thorpe Waterville and Achurch remained the property of the Crown until Henry VIII granted them to his illegitimate son Henry FitzRoy.
Edward VI awarded the manors to Sir William Cecil, later Lord Burghley, and they remained in the possession of his descendants the Earls of Exeter, until 1773, when the estates were sold to Thomas Powys of Lilford. Thomas Powys’ grandson was raised to the peerage as the first Lord Lilford in 1797.

## Notable people

* Robert Browne who had previously founded the Brownists, a forerunner of Congregationalism, was rector here from 1591 to 1631.
* William Peake – born in Achurch in 1603, became Lord Mayor of London in 1686.
* Edmund Quincy – ancestor of John Quincy Adams, sixth president of the United States, lived in the village prior to emigrating to America in 1633.
The village has lent its name to people's surnames who are believed to have originated from the village.

# Harold Wilson (rower)

Harold Charles Wilson (15 January 1903 – 2 May 1981) was an American rower and Olympian. He was born in Washington Boro, Lancaster County, Pennsylvania, the oldest child of William B. Wilson and Henrietta A. Charles. By 1910, his family had moved to Philadelphia, Pennsylvania, where he grew up.
Wilson was a member of the U.S. Olympic Team, representing the United States at the Games of the VIII Olympiad held in Paris, France from 4 May through 27 July 1924. He competed in the paired oar shell with coxswain rowing event (crew).
The boat included Wilson (stroke), Leon Butler (bow seat), and Edward Jennings (cox). Rowing out of the Pennsylvania Barge Club of Philadelphia, the crew qualified for the U.S. Olympic team on 13 June 1924 at national trials held in Philadelphia. At the Olympic Games, the boat came in third, earning a bronze medal on 17 July 1924 at the Argenteuil Basin on the Seine.
After the 1924 Olympic Games, Wilson made his home in Philadelphia. He married Virginia E. Harris née Gessing (25 October 1902 – 21 March 1986) in Manhattan, New York City, NY on 27 June 1931. They moved to the Philadelphia suburb of Laverock in 1949. With his father, he owned and operated the Fairhill Laundry at 241 W. Allegheny Avenue in North Philadelphia.
Wilson retired and closed the business in 1969. In his retirement, he lived in Beach Haven, New Jersey, dying there in 1981 at age 78. He is interred in a family plot in the Lawnview Memorial Park, Rockledge, Pennsylvania.
# Titanium(IV) hydride

Titanium(IV) hydride (systematically named titanium tetrahydride) is an inorganic compound with the empirical chemical formula TiH $_4$. It has not yet been obtained in bulk, hence its bulk properties remain unknown. However, molecular titanium(IV) hydride has been isolated in solid gas matrices. The molecular form is a colourless gas, and very unstable toward thermal decomposition. As such the compound is not well characterised, although many of its properties have been calculated via computational chemistry.

## Synthesis and stability

Titanium(IV) hydride was first produced in 1963 by the photodissociation of mixtures of TiCl$_4$ and H$_2$, followed by immediate mass spectrometry. Rapid analysis was required as titanium(IV) hydride is extremely unstable. Computational analysis of TiH$_4$ has given a theoretical bond dissociation energy (relative to M+4H) of 132 kcal/mole. As the dissociation energy of H$_2$ is 104 kcal/mole the instability of TiH$_4$ can be expected to be thermodynamic; with it dissociating to metallic titanium and hydrogen:
    TiH$_4$ → Ti + 2 H$_2$ (76 kcal/mole)
TiH$_4$, along with other unstable molecular titanium hydrides, (TiH, TiH$_2$, TiH$_3$ and polymeric species) has been isolated at low temperature following laser ablation of titanium.

## Structure

It is suspected that within solid titanium(IV) hydride, the molecules form aggregations (polymers), being connected by covalent bonds. Calculations suggest that TiH$_4$ is prone to dimerisation. This largely attributed to the electron deficiency of the monomer and the small size of the hydride ligands; which allows dimerisation to take place with a very low energy barrier as there is a negligible increase in inter-ligand repulsion.
The dimer is a calculated to be a fluxional molecule rapidly inter-converting between a number of forms, all of which display bridging hydrogens. This is an example of three-center two-electron bonding.
Monomeric titanium(IV) hydride is the simplest transition metal molecule that displays sd$^3$ orbital hybridisation.
