As Silicon Valley celebrates the 50th anniversary of the microprocessor, Madeleine Marshall recalls her early days as a mathematician at the Johns Hopkins University Applied Physics Laboratory working on one of the first commercially available microprocessors.  During her professional career as a mathematician, computer scientist, system engineer, and technical manager, Madeleine helped build the first miniaturized satellite navigation terminal (ancestor of the ubiquitous GPS navigators), a prototype of the first implantable insulin pump, a ship-based deep-ocean transponder survey system, instrumentation for Navy submarines, and a data system for the commercial trucking industry.  If asked, however, she will tell you that of the many projects she worked on, developing the ground systems used to launch and operate defense and scientific satellites were career highlights. 

A post-retirement course change took Madeleine to South Carolina and into the world of small business, where she co-owned a small construction services business for several years.  During this time, she also served on the Citizens Advisory Board to the Department of Energy at the Savannah River Site, and on the Boards of Directors for an afterschool program for disadvantaged children, the local arts council, and her local church.  Since returning to Maryland in 2017, Madeleine has renewed her interest in space exploration as a NASA consultant and subject matter expert in space mission operations.

Madeleine is a graduate of Smith College and Johns Hopkins University and has done post-graduate work in technical management, marketing, and music.  Madeleine and her husband raised their children in rural Howard County alongside innumerable dogs, cats, goats, various varieties of poultry, and horses.  Although no longer living a rural life, Madeleine enjoys gardening, cooking, sewing, and music in all its forms.
