Why did Werner Heisenberg receive the 1932 Nobel Prize in Physics?

Werner Heisenberg was awarded the 1932 Nobel Prize in Physics for his discovery of a method to formulate quantum mechanics using matrices.1

This groundbreaking work, often referred to as matrix mechanics, provided a new mathematical framework for understanding the behavior of subatomic systems by connecting the frequencies and intensities of spectrum lines. While Heisenberg is also widely recognized for his uncertainty principle published in 1927, the Nobel Committee specifically honored his foundational contribution to the development of quantum mechanics.12
