L-R: President Nelson Mandela, Dr. Bettye Walker, President, A-MAN, Inc., Prof. Hal Walker, Chairman.


As the world honors President Nelson Mandela, Professor Hildreth “Hal” Walker, Jr. and Dr. Bettye D.Walker, founders of A-MAN, Inc. a STEM International Science, Technology, Engineering, Mathematics education/mentoring agency based in Los Angeles, CA (USA). continue the promise to educate South African students.

In 1994, CA State Senator Diane Watson invited Professor Walker, a retired aerospace engineer from the Howard Hughes Aircraft Company, and wife Dr. Bettye a retired professor and public school administrator, to visit South Africa as part of a Los Angeles delegation. About 30 professionals traveled to determine the needs of the new South Africa and how to assist its people. Hal and Bettye were encouraged by what they saw and continually returned to South Africa to explore ways to utilize their expertise. While visiting the ANC Headquarters in Pretoria, South Africa in 1997, Hal and Bettye brought a group of 12 students, girls and boys, on a Study Tour along with their parents from Los Angeles. The students, 8 to13 years of age, were introduced to President Mandela. President Mandela was so impressed with these students that he delayed his next appointment. “He engaged them about their educational interest and their preparation for the future, says Hal Many of the students spoke about space technology and their ambitions in life. He then asked Prof. Hal and Dr. Bettye if they would “Promise” to come back and promote the AMAN, Inc. STEM program in South Africa for the 1998 year of “Science and technology”. President Mandela then posed for a picture with the Hal and Bettye and parents. Also, Vice President Thabo Mbeki met with the group. “We said yes, how could we refuse Nelson Mandela,” says Hal. Now for over 20 years Hal and Bettye commute to and from South Africa, “Keeping The Promise.”

Professor Walker was involved in many US National Technology laser projects. The most famous and historical is the 1969 NASA/ Apollo 11 first manned moon landing where he was responsible for the operations of the Lunar Laser Ranging System. This experiment represents the first Successful Interplanetary Laser Ranging Experiment in History over a round trip distance of nearly 500 Thousand Miles. Hal’s laser Ranging Experiment was recognized recognized in 1994 in a permanent exhibit “Science in American Life” at the National Smithsonian Institution’s Museum of American History.

The A-MAN, Inc. Science and Technology program was established in 1986 in Carson, CA as a research grant funded by UCLA and directed by Dr. Bettye Walker. The very successful project was created to study the educational decline of Inner City students and develop advanced models to improve their educational interest and performance. Science and technology was chosen as the student’s motivational tool starting from 5-18 years of age. Over 10,000 A-MAN, Inc. students have graduated from Universities and Colleges in the US.

Along with partner Rotary International, initially Hal and Bettye worked at the Sammy Marks Farm school. This project culminated in a new law that electrified all farm schools across SA. Today A-MAN is affiliated with over 20 sites in South Africa. These schools are located in the Pretoria, Johannesburg and Cape Town areas. A-MAN SA is a Section 21 Association based in Cape Town. Across South Africa thousands of students have benefited from new computer literacy labs, technology learning sessions and motivational talks given by Prof Hal and Dr. Bettye.

Hal says that it was President Mandela’s vision to bring South Africa’s education system into the 21st century using new learning methods. There was an educational gap in the country. He saw those A-MAN youngsters, as a model of what can be done with the youth of South Africa to build the next technological generation of South Africans.

Some of “The Promise” success examples have been: A-MAN SA had its first Ph.D. student graduate in computer science and in 2004 a 14 year old girl student from Fezeka High School in Gugulethu travelled to America and participated in a historical Jr. Astronaut JPL/NASA MARS Rover program. While there at NASA she actually pushed buttons that moved the MARS Rover on the planet surface. She is now a University of the Western Cape Honours graduate in Geology.

In addition, Prof Walker was instrumental in founding and chartering the Cape Town-Western Cape Alumni Chapter of Kappa Alpha Psi Fraternity, Inc., the first on the African Continent. The question is “where do we go from here in South Africa,” says Hal. “We must make sure there are sustained STEM educational programs as well as develop technological based jobs in South Africa. Hal says we will continue the “Mandela’s Promise” through our Educational STEM models, Rotary International educational projects, Private sector partners and most importantly showcasing the AMAN SA students and their families.

Presently, Hal and Bettye along with local community organizations such as Rotary International and private sector company’s such as DONIX are training 4 high school girls and boys from Cape Town to attend the 31st Annual International Space Development Conference (ISDC) in Los Angeles CA, USA in May 2018.these students attended the elementary school where Hal and Bettye partnered with Rotary International to establish a state of the art Computer Literacy Lab . These students have continued to have an interest in Science and Technology through the years of being prepared by Hal and Bettye at their primary and junior primary and now at the high school level. This South Africa STEM Student Achievers (SSA) the promiseTeam will lead and Exhibit during the Conference. This event will bring together leading space technologies professional managers, engineers, astronauts, scientists, STEM educators, the next generation of STEM students and business people from around the world. Students will participate in discussions, view exhibits on space settlements and hear about human space flight and future space developments. Tours are planned to facilities such as JPL/NASA, Space X and other technology Science Centers. On their return to SA the students will participate in lectures to other students and teachers at local school programs to motivate other students. They will also speak to Rotary Club meetings, and community groups to spread the wealth of knowledge that they have gained as well as their experiences. This preparation will enhance the future of South Africans in space development and space related business enterprises.
