"[Martin Thurwanger] described to me his works, which I confess were truly lovely. They were chromolithographs, reproductions of paintings that could be confused with the original . . . I expressed my interest in learning that craft, and more still, that since I was unemployed, I would have accepted work for very little."
In spring 1873, Juglaris met the well-known Paris lithographer Martin Thurwanger, whose wife was the cousin of the eminent French artist Jean-Baptiste Camille Corot. He introduced Juglaris to the techniques of chromolithography, a method of color printing that produced unusually rich and striking results. It was another rapidly growing field of industrial art. Juglaris was glad for the exposure which was to considerably aid his career.
Martin Thurwanger and his brother Peter held Juglaris in high regard. Over the next seven years, they warmly welcomed him into their family life. In many ways they served as his patrons. Besides hiring him for their own lithography projects, they introduced him to Parisian society generally and recommended him for important commissions. It was thanks to the Thurwangers that Juglaris found ongoing employment as an historical illustrator with Firmin-Didot, the prominent Parisian publishing house. For the next three years, Firmin-Didot called upon Juglaris to prepare a wide array of watercolors for Charles-August Racinet’s magisterial six-volume Le Costume Historique. To this day the encyclopedic set is regarded as one of the finest illustrated histories of world costume ever produced. For his own part as an exacting and meticulous artist, Juglaris consulted available museum collections across France to ensure the authenticity of the costume details he was incorporating in each watercolor.
Beyond his work as a ceramicist, lithographer, and illustrator, Juglaris designed furniture and produced "cartoons" or patterns for stained glass windows. His work in the realm of industrial arts compensated him so well that he was able to pay off his father’s 2000 lire debt back home, redeeming the family’s honor.
