Langford trained as an industrial chemist and was a member of Royal Chemical Society. In later life he turned to mathematics, and published thirty articles in the Mathematical Gazette. One of these (‘Problem’) appeared in 1958 and concerned what came to be known as the Langford Sequence. Its significance is discussed by Martin Gardner, in his ‘Mathematical Magic Show’ (1978). Both items aged and creased, with closed tears, but with text complete and legible. Both are addressed to ‘Dear Sir Richard’ and signed ‘C Dudley Langford’. ONE: 3pp, 12mo. On two leaves.

3pp, 12mo. Bifolium. In good condition, lightly aged. The letter begins with a reference to 'Mrs Baker's death'. Pearson and his wife 'had not realised the gravity of her illness', as they had recently seen her 'so well and fresh in spirit'. He wishes he had been able to accept Peirce's suggestion of 'putting me up for tonight' in order to be 'present tomorrow', but he is 'overdone and had work till 6 o'clock arranged for today, so that to come down by the night train tonight & track back tomorrow night have been more than I could safely attempt'.

2pp., 12mo. In good condition, lightly aged. Writing in the year before his elevation to the bishopric, Goodwin writes: 'I do not know whether you dabble at all in Algebra; if you do, you may like to have the mathematical investigation of the problem of the blind-gaoler, which I inclose - It exhibits distinctly the limits of the problem & shews how others of the same kind might be constructed'.

In fair condition, lightly aged and worn. He begins by reassuring Harington that his books are 'safely here', but continues: 'I fear that every book I possess on numerical equations is on duty for the time being in the computing department of one of the RAF establishments.' He does not know of 'any book which gives an account of the processes actually used nowadays.

In two columns, on one side of piece of 50 x 30.5 cm paper. Aged and worn, with chipping and loss to margins. Two pencil notes in margin: 'this was ommitted [sic]' and 'the truth acquired mostly forgotten'. Clearly not intended for publication, and apparently the advice of a knowledgeable and well-educated man of scientific bent to his family, regarding the future of 'Charlie' (his grandson?). A reference to Clifton College may suggest a West Country origin. The piece begins: 'The subject of Education is in a great state of confusion, and great diversities of opinion exist about it.

Inglis considers that 'Mr. R. seems to have hit upon something he does not quite comprehend'.
