We were involved in the building of lasers… we were developers and producers of very sophisticated laser equipment in those early days.

It was pretty lonely experience for myself in laser technology [as an African American involved in science].
— Professor Hildreth “Hal” Walker

We are here because Nelson Mandela invited us to come and work with the children here and promote science and technology.
— Dr. Bettye D.Walker

We’ve graduated over 10 000 students from the universities and colleges throughout the US, and some even here in South Africa.
