The individual often referred to as the father of modern lighting design is Inigo Jones. He was an English architect and designer during the 16th to 17th centuries, notable for his pioneering work in the integration of light into architectural design. Jones introduced the concept of using natural light as an integral aspect of design in his buildings, particularly through the use of large windows and open spaces. His approach to lighting emphasized not only functionality but also the aesthetic quality of light, which paved the way for modern practices in interior design and architecture. In more recent history, designers like Louis Kahn and others have also been recognized for their contributions to lighting design, but it is Inigo Jones who is often credited as a foundational figure in this field.
