Information is scarce (Dodgson's diaries for the years 1858–1862 are missing), but it seems clear that his friendship with the Liddell family was an important part of his life in the late 1850s, and he grew into the habit of taking the children on rowing trips (first the boy, Harry, and later the three girls) accompanied by an adult friend [42] to nearby Nuneham Courtenay or Godstow. [43] An Elementary Treatise on Determinants, With Their Application to Simultaneous Linear Equations and Algebraic Equations Cohen goes on to note that Dodgson "apparently convinced many of his friends that his attachment to the nude female child form was free of any eroticism", but adds that "later generations look beneath the surface" (p.229). He argues that Dodgson may have wanted to marry the 11-year-old Alice Liddell and that this was the cause of the unexplained "break" with the family in June 1863, [29] an event for which other explanations are offered. Biographers Derek Hudson and Roger Lancelyn Green stop short of identifying Dodgson as a paedophile (Green also edited Dodgson's diaries and papers), but they concur that he had a passion for small female children and next to no interest in the adult world.

Flodden W. Heron, "Lewis Carroll, Inventor of Postage Stamp Case" in Stamps, vol. 26, no. 12, 25 March 1939 He left Rugby at the end of 1849 and matriculated at the University of Oxford in May 1850 as a member of his father's old college, Christ Church. [17] After waiting for rooms in college to become available, he went into residence in January 1851. [18] He had been at Oxford only two days when he received a summons home. His mother had died of "inflammation of the brain" – perhaps meningitis or a stroke – at the age of 47.

A study by Roger Taylor and Edward Wakeling exhaustively lists every surviving print, and Taylor calculates that just over half of his surviving work depicts young girls, though about 60% of his original photographic portfolio is now missing. [61] Dodgson also made many studies of men, women, boys, and landscapes; his subjects also include skeletons, dolls, dogs, statues, paintings, and trees. [62] His pictures of children were taken with a parent in attendance and many of the pictures were taken in the Liddell garden because natural sunlight was required for good exposures.

In his diary for 1880, Dodgson recorded experiencing his first episode of migraine with aura, describing very accurately the process of "moving fortifications" that are a manifestation of the aura stage of the syndrome. [111] There is no clear evidence to show whether this was his first experience of migraine per se or he previously had the far more common form of migraine without aura, although the latter seems most likely, given the fact that migraine most commonly develops in the teens or early adulthood. Another form of migraine aura called Alice in Wonderland syndrome has been named after Dodgson's book of the same name and its titular character because its manifestation can resemble the sudden size-changes in the book. It is also known as micropsia and macropsia, a brain condition affecting the way that objects are perceived by the mind. For example, an affected person may look at a larger object such as a basketball and perceive it as having the size of a golf ball. Some authors have suggested that Dodgson experienced this type of aura and used it as an inspiration in his work, but there is no evidence that he did. [112] [113]Greenarce, Selwyn (2006) [1876].
