William Willard (deaf educator)
William Willard( November 1, 1809 – February 15, 1881) founded Indiana's school for the deaf in Indianapolis, Indiana, which later became the Indiana School for the Deaf.
He was one of the most important deaf persons in the deaf community.
Willard was born on November 1, 1809 in Brattleboro, Vermont.
He grew up in Rockingham, Vermont, and attended American School for the Deaf in Hartford, Connecticut.
During his schooling, he was a student of the famous Laurent Clerc, who was and is considered the" Father of Deaf Education" in America.
After he graduated, he taught at a school for the deaf in Columbus, Ohio, which was called Ohio School for the Deaf.
There, he met Eliza Young, who was also deaf and a teacher, and married her.
Eventually, the both of them traveled to Indianapolis, Indiana, and William proposed the establishment of a school for the Deaf.
He and Eliza traveled throughout the state of Indiana on horseback, recruiting potential deaf students in order to form a school.
On October 1, 1843 was the first day of school, and William's school had twelve students.
William and his wife, Eliza, both were teachers.
Eventually, Indiana passed a law that established the school as a state institution, and after William became Principal of the school, Indiana passed a law that officially declared Indiana School for the Deaf as the sixth state school for the Deaf to provide free education to all deaf and hard of hearing students.

Bengt Snivil
Bengt Snivil (also known as "Bengt Snivel") from the House of Bjelbo was a Swedish magnate in mid-12th century.
Some more or less romantic later literature has given him the title of jarl, although no proper historical source attests to such.
Romantic genealogies assign a lady Sigrid Lakman as his wife, though without historical source.
Arguably, Bengt Snivil was that Bengt or Benedict, who was son of
riksjarl Folke the Fat and Ingegerd Knutsdotter of Denmark, daughter of king Canute IV of Denmark.

Charles the Child
Charles the Child( Latin" Karolus puer", from the" Annales Bertiniani"; 847/848, Frankfurt am Main – 29 September 866, Buzançais) was the King of Aquitaine from October 855 until his death in 866.
He was the second son of Charles the Bald and brother of Louis the Stammerer.
The younger Charles was appointed by his father, who had previously ruled as King of Aquitaine himself from 838, as a sop to Aquitainian separatism.
The Aquitainians had previously rebelled against Charles the Bald, requesting from Louis the German that he send one of his sons to rule over them.
Louis had sent his second son, Louis the Younger, prompting Charles the Bald to release his rival claimant to Aquitaine, Pippin II.
Pippin succeeded in rallying the nobles to support himself and Charles the Bald against Louis the Younger, who was driven out.
By October, however, Pippin lost his popularity with the still- rebellious Aquitainians, prompting Charles the Bald to appoint Charles the Child as King.
Charles the Child was duly anointed at Limoges.
Within a year, he had been replaced by the Aquitainians with Pippin II.
These same then deposed Pippin and restored Charles the Child.
Pippin was captured in 864 and imprisoned at Senlis, at which point he disappears from history.
Unlike previous sub-kings of Aquitaine,( Louis the Pious, Pippin I, Pippin II), Charles the Child had no real authority at all.
Before 840, the kingdom had been ruled in person by an autonomous king; Charles the Bald, however, after his accession as King of Western Francia, attempted to maintain power in Aquitaine.
Consequently, Charles the Child, and his brother, Louis the Stammerer, did not rule in person, had no chancery, could issue no instruments; they were no longer empowered to bestow privileges, endow religious establishments, or dispose of royal property.
All the rights of the region were invested in Charles the Bald, in whose absence the nobles of the Kingdom gathered power.
Nonetheless, as Charles grew older, he began to exercise what little personal authority he could.
For example, in 862 he chose and married a wife against the will of his father.
The name of his wife is unknown, although she was apparently the widow of a count named Humbert.
Charles the Bald reasserted his power over his son in 863, forcing the younger Charles to put away his wife and be loyal to his father.
A year later, he was accidentally struck with a sword in the head by a member of his own hunting party in a mock combat, leading Ado of Vienne to say that" Charles was dishonoured(" dehonestatus") by having suffered it".
The blow left him mentally incapacitated until his resultant death in 866.
He died childless and was buried in Bourges.

Charles the Deaf
Charles the Deaf  from the House of Bjelbo was the jarl of Sweden during 1216–1220.
His father was magnate Bengt Snivil.
He was the brother of Magnus Minnesköld and jarl Birger Brosa and father of jarl Ulf Fase.
Charles died at the Battle of Lihula in Estonia August 8, 1220.
The seal of Charles, discovered in the early 1990s, is dated to the end of the 12th century and thus the oldest preserved personal object in Swedish history.
Personal seals were normally broken to pieces at the death of the owner in order to prevent later abuse, and the intact seal of Charles is therefore unique.
The Swedish Museum of National Antiquities bought it in 2001 for SEK 800,000.
