Sylvan Nathan Goldman, born in 1898, was an American businessman and inventor best known for revolutionizing the retail industry with his invention of the shopping cart. Raised in the Jewish faith, he learned the retail trade from his family and served in World War I as a food requisitionist in France. In 1920, Sylvan and his brother established the state's first supermarket, the Sun Grocery Company, and quickly expanded to operate multiple stores. Following the stock market crash in 1929, they formed a new company, Standard Grocery, and later merged with the Humpty-Dumpty grocery store chain. It was in 1937 that Sylvan introduced the first shopping cart, designed to alleviate the difficulty women faced with the self-serve concept. Despite initial resistance, the shopping cart became a huge success, earning Goldman a significant royalty on every folding design shopping cart in the United States and making him a multimillionaire. He also manufactured the more modern "nesting cart" and patented the "Nest-Kart" in 1948. Sylvan Nathan Goldman's innovative contributions to the retail industry have left a lasting impact, shaping the way people shop to this day.

A sylvan theater, also known as a greenery theater, is an outdoor theater set in a wooded (sylvan) environment, often adorned with classical motifs and elaborate arrangements of shrubs and flowers. These alfresco stages can be found in formal gardens, parks, or intimate settings and may be intended for public or private use. One notable early example is the Bosquet du Théâtre d’Eau in the Gardens of the Palace of Versailles, designed for King Louis XIV. Notable sylvan theaters in Europe include the Sylvan Theater at Killruddery House and Gardens in Ireland and the Ruinentheater in Sanspareil Garden, Germany. In North America, examples include the National Sylvan Theater in Washington, DC, and the Forest Theater in Carmel, California. These theaters provide unique outdoor performance spaces that blend nature and art, offering audiences a memorable cultural experience.
