Some years later, Frutiger was commissioned to develop a typeface for Roissy Airport. Frutiger had earlier created an alphabet inspired by Univers and Peignot for Paris Orly Airport, but found the experience a failure due to lack of control and the insistence that all text be in capitals only. As a result, he proposed a modified version of Concorde, refining it following research into legibility. The Roissy typeface was completed in 1972. Impressed by the quality of the Roissy airport signage, the typographical director of the Mergenthaler Linotype Company approached Frutiger in 1974 to turn it into a typeface for print.
