This early work on physiognomy, which has not been translated into English, is distinct from Lavater's more comprehensive treatment of the subject, which appeared in multiple English editions under the title Essays on Physiognomy.19 Alphonse Bertillon, La photographie judiciare avec un appendice sur la classification et l'identification anthropométrique (Paris: Gauthier-Villars, 1890), 17.20 Here one could add yet a third level of meaning to the concept, which concerns the grooved or “profile” bicycle tires first patented by Dunlop or Palmer in 1880. In the Sherlock Holmes story “The Adventure of the Priory School,” it is the interpretation of these peculiar treads near the crime scene that sets the detective on the right track toward finding the missing pupil. At one point in the investigation, Holmes remarks: “I am familiar with forty-two different impressions left by tyres.” Quoted from Arthur Conan Doyle, “The Adventure of the Priory School,” in The Return of Sherlock Holmes (New York: A. Wessels, 1907), 119–58, at 136.21 For a screenshot of Match.com's homepage from 1995, see Mia de Graaf, “‘I Was Trying to Find the Right Person to Marry’: Match.com Co-Founder Reveals the Inspiration of Online Dating Site as It Goes Public,” Daily Mail (November 19, 2015): www.dailymail.co.uk/sciencetech/article-3324447/I-trying-right-person-marry-Match-com-founder-reveals-inspiration-online-dating-site-goes-public.html.

For a report about using the site, see Leslie Crawford, “Geek Love,” San Francisco Focus (October, 1996), 20: “You simply post your profile on-line and wait for the on-line love letters.”22 See Eva Illouz, Cold Intimacies: The Making of Emotional Capitalism (Cambridge: Polity, 2007), 74–114; and Illouz, Why Love Hurts: A Sociological Explanation (Cambridge: Polity, 2012), 198–237.23 See youtube.com/watch?v=MzE2cOqUFWM, at the 2:20 mark.24 Older online communities such as WELL (“Whole Earth 'Lectronic Link”), which was founded in California in 1985, did not make use of the profile format. Members dialed in with a user name and password and could comb through various thematically arranged sites and post comments.
