Cathy, you need to restrict your search to English only then in the advanced options of your chosen search engine.
This is what I have been able to glean :
Jaroslav Brychta ( 1895-1971 ), trained as a sculptor at the Prague Academy of Applied Arts. In 1920 he co-founded and was a professor at the Specialized Glass School (a trade school) in Zelezny Bröd which produced mainly buttons, fashion jewellery and lamp-worked figures.
He is well-known for his fanciful lampwork and I suspect that the reason why most of the figures you have seen are attributed as "in the style of", is because its impossible to know if any given piece was actually made / designed by him, or by one of his students at the school.
Artistically he has been overshadowed by his talented daughter Jaroslava Brychtová (b. 1924). Together they founded a glass casting facility at Zdenek Lhotsky in the late 1940s. It remains the only foundry in the world capable of casting glass on a monumental scale. She went on to become one of the most influential Czech glass artists of the 20th century, another being her partner Stanislav Libensky (1921-2002).
A paper on Jaroslav Brychta: Glass Figurines by Joy Kelley was included in the journal of The Glass Art Society 30th Annual Conference G.A.S. 2000: Brooklyn, New York.
He is featured in BOHEMIAN GLASS 1400-1989 by Sylva Petrova and Jean-Luc Olivie, Harry N. Abrams, Inc., NY, 1989 (subsequently published in 1990 as BOHEMIAN GLASS, Flammarion, Paris), which presents the English language version of a volume commemorating the 1989 Exhibition Verres de Boheme, 1400-1989., organized jointly by the Musee des Arts decoratifs in Paris and the Museum of Decorative Arts of Prague. Several books have been published on him in the Czech language.
