## Body
### Early Life and Education
Henry MacKay Walker was born in 1947. He completed his undergraduate education at Williams College, earning a Bachelor of Arts in Mathematics in 1969. During his time at Williams, he also served as an instructor from 1968 to 1969, demonstrating early interest in academia. After graduation, he briefly worked at Mobil in 1969 before pursuing graduate studies.

### Graduate Studies and MIT
Walker enrolled at the Massachusetts Institute of Technology for his doctoral studies, where he earned his Ph.D. in Mathematics in 1973. His doctoral advisor was Franklin P. Peterson, a notable mathematician known for his work in algebraic topology. During his time at MIT, Walker was affiliated with the institution from 1973 to 1974, likely as a postdoctoral researcher or visiting scholar.

### Career at Grinnell College
In 1974, Walker joined the faculty at Grinnell College, a private liberal arts college in Iowa. He would remain there for the rest of his career until retiring in 2021. During his 47-year tenure, he witnessed and contributed to the evolution of computer science from an emerging field to a central discipline of the digital age. His long-standing presence at the institution suggests he played a crucial role in developing and maintaining the computer science program.

### Academic Identity
Throughout his career, Walker maintained identities as both a mathematician and computer scientist. While his doctoral work was in pure mathematics, his master's degree from the University of Iowa (completed in 1979, six years after his Ph.D.) was in computer science. This combination of mathematical rigor and computational thinking positioned him uniquely to teach theoretical computer science and help students understand the mathematical foundations of algorithms and computation.
