Randomly selected from a pool of New Orleans–based topics, this study explores the local and global evolution of Venetian blinds, focusing on the 1841 patent granted to John Hampson in Carrollton, Louisiana. While there are documented records of slatted window coverings in Europe and the Middle East dating back centuries, Hampson is widely credited with patenting the first mechanism that allowed the slats to be held at adjustable angles—a design that laid the foundation for modern Venetian blinds. Through patents, trade catalogs, and manufacturer innovations, this research traces the transformation of a simple shading device into a mass-produced architectural element with enduring global impact.
