The M. M. (Michael Maurice) O'Shaughnessy papers, 1882-1937, consist of materials relating to his career as a civil engineer, working first as a consultant in private practice, and later as City Engineer of San Francisco. The collection contains primary and secondary source materials both created and collected by O'Shaughnessy in the course of planning, conducting, and overseeing a large range of engineering projects, and later kept as part of his own private files. His writings include typescripts and published versions of many speeches, articles, and books by O'Shaughnessy—both in his role as City Engineer, and as a consulting engineer who was active at the national and local level in professional organizations and societies. With these are his engineering notes and notebooks, a collection of reference materials, and a small amount of personal and family papers.

Michael Maurice (M. M.) O'Shaughnessy was born in Limerick, Ireland, on May 28, 1864, the son of Patrick and Margaret (O'Donnell) O'Shaughnessy. One of nine children, he was educated in the public schools in Ireland, and attended Queen's College, Cork, and then in Galway. He graduated with honors from the Royal University, Dublin on October 21,1884, and received the degree of Bachelor of Engineering.
