As UX design evolved, new figures emerged that helped build this field. Some of the major contributors to UX design include:

• Don Norman: He is a cognitive scientist and usability engineer who, while working at Apple in the 1990s, coined the term "User Experience." He also adopted the title "User Experience Architect" and became the first known specialist to use this term in the field of UX.
• Jakob Nielsen: Known as the "king of usability," Nielsen is a computer scientist who defined the principles (known as Nielsen's heuristics) that guide how we create user-friendly interfaces.
• Alan Cooper: Referred to as the "Father of Visual Basic," Cooper has made significant contributions to the UX field, including introducing the concept of personas.
