James Herbert McNair (23 December 1868 – 22 April 1955), was a Scottish artist, designer and teacher whose work contributed to the development of the Modern Style (British Art Nouveau style) during the 1890s.
As part of their training, the two attended evening classes at the Glasgow School of Art between 1888 and 1894, and it was there that they met the MacDonald sisters, Margaret and Frances.
McNair set up his own studio in Glasgow in 1895, where he worked as a designer producing furniture, book illustrations, water colours and posters.
McNair’s artistic merits have often been compared unfavourably to those of Mackintosh, but he had significant influence as a teacher following his move to Liverpool in 1898 and appointment as Instructor in Design at the School of Architecture and Applied Art.
Following closure of the School in 1905, and the loss of the McNair family wealth through business failure, the couple returned to Glasgow in 1909.
