Ada Lovelace is one of the most important people in IXD because she helped formulate to bring the “IX” in ixd to life. 

As someone who believed that compute was more than just numbers, she helped progress the complex systems thinking to adopt symbols, music, art and other areas of science. 

Her keen interest pushed the boundaries in data processing, cryptography but most importantly, AGI (not in those exact words) 

Without these algebraic computations, it would be impossible for us to run our designs on Figma and bring them to web versions in real time, In real life. 

Lillian Gilberth deserves huge praise in terms of bringing the D to “IXD”, simply because she helped pioneer and innovate in ergonomic and functional design which has helped us propel the way we think of life. 

Her keen attention into (human centred design) allows people today to design keeping in mind various stakeholders as well as motivate them to use it with ease due to the psychology behind it.

Without these two, we might not have IX D.
