The Life of Charlotte Brontë, the posthumous biography of Charlotte Brontë by Gaskell, was the first of many biographies about Charlotte to be published. Though frank in places, Gaskell suppressed details of Charlotte's love for Heger, a married man, as being too much of an affront to contemporary morals and as a possible source of distress to Charlotte's still-living friends, father and husband.
Charlotte continued to write to C. Heger well into 1845.
Charlotte's portrayal of the temperamental M. Heger as she first saw him in 1842 describes a striking man:
“He is professor of rhetoric, a man of power as to mind, but very choleric and irritable in temperament; a little black being, with a face that varies in expression. Sometimes he borrows the lineaments of an insane tom-cat, sometimes those of a delirious hyena; occasionally, but very seldom, he discards these perilous attractions and assumes an air nor above 100 degrees removed form mild and gentlemanlike.
Later letters to Constantin Heger.
“If my master withdraws his friendship from me entirely I shall be altogether without hope; if he gives me little – just a little – I shall be satisfied – happy; i shall have reason for living on, for working .... Nor do I, either, need much affections from those I love .... But you showed me of yore a little interest, when I was your pupil in Brussels, and I hold on to the maintenance of that little interest – I hold on to it as I would hold on to life.
