According to Jane Spillman's book, Glass from World's Fairs 1851-1904, and an article from the 1889, vol 10, no 6 issue of Revue des Arts Decoratifs, the following glassmakers were exhibiting:
Thomas Webb & Sons
MM. Appert Freres
MM James Vidie et fils
Landier et Houdaille
I am sure there were others! These are the ones I found doing a quick search of the literature about this exposition. I am attaching a bibliography of materials about the 1889 exposition, in case you need more information about the exhibitors.
Please let me know if you have other questions!
