Designer Spotlight: Tiffany Studios

  • Designer Spotlight
  • Modern + Contemporary

Louis Comfort Tiffany was a prolific American designer whose career spanned from the 1870s–1920s. While he was most well known for his stained glass, he produced pieces in a variety of mediums, including pottery, metalwork, and lighting.

At the close of the 19th century, Louis Comfort Tiffany first developed Favrile glass. Deeply impressed from a recent trip to Europe in the 1860s, Tiffany drew inspiration from Roman and Syrian glass making. After much experimenting, Tiffany’s technique of ingraining color within the glass set it apart from other types of iridescent glass, resulting in the beautiful distinctive hues of Favrile glass.

Tiffany was also largely inspired by nature – he was captivated by the array of lush colors of flowers and plants. This attraction to color also contributed to the brilliant shades featured in Favrile glass objects.

Tiffany went on to win a grand prize at the 1900 Paris Exposition (the World’s Fair), for his Favrile glass. Later, he began producing lamps and large stained-glass Favrile pieces, cementing himself as one of the most influential figures in the Art Nouveau style through to the Arts and Crafts period.

Although it originally opened in 1837 as a stationary and fancy goods store in New York City, Tiffany & Co. was clearly destined for more. Founder, Charles Lewis Tiffany, also known as the “King of Diamonds,” spearheaded the discovery and exploration of rare gemstones — going as far as to introduce the world to never-before-seen gemstones along with his Tiffany gemologists.

For example, Dr. George Frederick Kunz, a Tiffany gemologist, discovered the new specimens of kunzite in 1902 and morganite in 1910. Following this tradition of discovery, the Tiffany team founded both tanzanite and tsavorite, bringing them to the public eye in 1968 and 1974, respectively.
