Answer by taking a quote from the following article:

Charles Lutwidge Dodgson (; 27 January 1832 - 14 January 1898), better known by his pen name Lewis Carroll, was an English writer, mathematician, logician, Anglican deacon, and photographer. His most famous writings are Alice's Adventures in Wonderland, its sequel Through the Looking-Glass, which includes the poem "Jabberwocky", and the poem The Hunting of the Snark - all examples of the genre of literary nonsense.

Dodgson's family was predominantly northern English, with Irish connections, conservative and High Church Anglican. Most of Dodgson's male ancestors were army officers or Church of England clergy. His great-grandfather, also named Charles Dodgson, had risen through the ranks of the church to become the Bishop of Elphin. His paternal grandfather, another Charles, had been an army captain, killed in action in Ireland in 1803 when his two sons were hardly more than babies. The older of these sons - yet another Charles Dodgson - was Carroll's father. He went to Westminster School and then to Christ Church, Oxford. He reverted to the other family tradition and took holy orders. He was mathematically gifted and won a double first degree, which could have been the prelude to a brilliant academic career. Instead, he married his first cousin Frances Jane Lutwidge in 1827 and became a country parson.  Dodgson was born in the small parsonage at Daresbury in Cheshire near the towns of Warrington and Runcorn, the eldest boy but already the third child of the four-and-a-half-year-old marriage. Eight more children followed. When Charles was 11, his father was given the living of Croft-on-Tees in North Yorkshire, and the whole family moved to the spacious rectory. This remained their home for the next 25 years.  Charles's father was an active and highly conservative cleric of the Church of England who later became the Archdeacon of Richmond and involved himself, sometimes influentially, in the intense religious disputes that were dividing the church. He was high church, inclining to Anglo-Catholicism, an admirer of John Henry Newman and the Tractarian movement, and did his best to instil such views in his children. Young Charles was to develop an ambiguous relationship with his father's values and with the Church of England as a whole.  The young adult Charles Dodgson was about 6 feet (1.83 m) tall and slender, and he had curly brown hair and blue or grey eyes (depending on the account). He was described in later life as somewhat asymmetrical, and as carrying himself rather stiffly and awkwardly, although this might be on account of a knee injury sustained in middle age. As a very young child, he suffered a fever that left him deaf in one ear. At the age of 17, he suffered a severe attack of whooping cough, which was probably responsible for his chronically weak chest in later life. Another defect which he carried into adulthood was what he referred to as his "hesitation", a stammer that he acquired in early childhood and which plagued him throughout his life.  The stammer has always been a significant part of the image of Dodgson. It is said that he stammered only in adult company and was free and fluent with children, but there is no evidence to support this idea. Many children of his acquaintance remembered the stammer, while many adults failed to notice it. Dodgson himself seems to have been far more acutely aware of it than most people whom he met; it is said that he caricatured himself as the Dodo in Alice's Adventures in Wonderland, referring to his difficulty in pronouncing his last name, but this is one of the many "facts" often repeated for which no first-hand evidence remains. He did indeed refer to himself as the dodo, but whether or not this reference was to his stammer is simply speculation.  Dodgson's stammer did trouble him, but it was never so debilitating that it prevented him from applying his other personal qualities to do well in society. He lived in a time when people commonly devised their own amusements and when singing and recitation were required social skills, and the young Dodgson was well equipped to be an engaging entertainer. He reportedly could sing tolerably well and was not afraid to do so before an audience. He was adept at mimicry and storytelling, and was reputedly quite good at charades.  In broad terms, Dodgson has traditionally been regarded as politically, religiously, and personally conservative. Martin Gardner labels Dodgson as a Tory who was "awed by lords and inclined to be snobbish towards inferiors." The Reverend W. Tuckwell, in his Reminiscences of Oxford (1900), regarded him as "austere, shy, precise, absorbed in mathematical reverie, watchfully tenacious of his dignity, stiffly conservative in political, theological, social theory, his life mapped out in squares like Alice's landscape." Dodgson was ordained a deacon in the Church of England on December 22, 1861. In The Life and Letters of Lewis Carroll, the editor states that "his Diary is full of such modest depreciations of himself and his work, interspersed with earnest prayers (too sacred and private to be reproduced here) that God would forgive him the past, and help him to perform His holy will in the future." When a friend asked him about his religious views, Dodgson wrote in response that he was a member of the Church of England, but "doubt[ed] if he was fully a 'High Churchman'". He added:  I believe that when you and I come to lie down for the last time, if only we can keep firm hold of the great truths Christ taught us--our own utter worthlessness and His infinite worth; and that He has brought us back to our one Father, and made us His brethren, and so brethren to one another--we shall have all we need to guide us through the shadows. Most assuredly I accept to the full the doctrines you refer to--that Christ died to save us, that we have no other way of salvation open to us but through His death, and that it is by faith in Him, and through no merit of ours, that we are reconciled to God; and most assuredly I can cordially say, "I owe all to Him who loved me, and died on the Cross of Calvary."  Dodgson also expressed interest in other fields. He was an early member of the Society for Psychical Research, and one of his letters suggests that he accepted as real what was then called "thought reading". Dodgson wrote some studies of various philosophical arguments. In 1895, he developed a philosophical regressus-argument on deductive reasoning in his article "What the Tortoise Said to Achilles", which appeared in one of the early volumes of Mind. The article was reprinted in the same journal a hundred years later in 1995, with a subsequent article by Simon Blackburn titled "Practical Tortoise Raising".
