Here is Thomas Carlyle's description of a meeting with William Godwin:
"He is a bald, bushy-browed, thick, hoary, hale little figure with spectacles: taciturn enough, and speaking when he does speak with a certain epigrammatic spirit; wherein except a little shrewdness there is nothing but the most commonplace character. (I should have added that he wears spectacles, has full grey eyes, a very large blunt characterless nose, and ditto chin.) By degrees I hitched myself near him, and was beginning to open him, and open on him, for he had stared twice at me; when suddenly enough began a speaking of French among the Kennys and Badamsinas (for they are all French-English); and presently Godwin was summoned off to—take a hand at whist! I had already flatly declined. There did the Philosopher sit, and a swarm of noisy children, chattering women, lounging dilettantes round him; and two women literally crashing hoarse thunder out of a piano (for it was louder than an iron-forge), under pretext of its being music by Rossini. I thought of my own piano, and the far different fingering it got; looked sometimes not without sorrow at the long-nosed whist-player; and in the space of an hour (seeing supper about to be laid in another room) took myself away."
