Підтримка:The author is grateful to Longin Lisetski who raised this issue to the author during Soft Matter Workshop at the Institute for Condensed Matter Physics in Lviv in 2008. Later this was discussed by author with Ivan Smalyukh during 2009 visit to the Liquid Crystal Materials Research Center at University of Colorado in Bolder.
Brief review of the literature on the history of thermotropic liquid crystal discovery and the role of the observations reported by Julius Planer in his note published almost 150 years ago.
