To begin with, I totally support that Ada Lovelace and Lillian Gilbreth are significant figures in Interaction Design History, not only for their pioneering contributions that influence modern design principles, but also for their way opened for women to be engaged into this industry.


Ada Lovelace is considered the world’s first computer programmer. Her work on Charles Babbage’s Analytical Engine, where she envisioned the machine’s potential beyond mere calculations, laid the groundwork for computational thinking, an essential aspect of digital interface design. Even though she was born in a well-educated family with resources with poetry and science, her mother lead her to the way of science, which could probably make her different from the other ladies in her age or with similar background)


Moreover, Lillian Gilbreth is a pioneer in human factors and ergonomics, Gilbreth introduced ideas about user-centred design. She studied how people interact with machines and environments, which is foundational to IXD. Her focus on improving efficiency and comfort influenced how we design tools and interfaces that consider the user’s needs and behavior.
