Johnson made a lawnmower engine from a scrap yard and fixed it on a go-kart. Out of excitement, Johnson drove the lawnmower on the highway, and the police pulled him over.

During his teen ages, Johnson developed a curiosity about how things function and anticipated becoming a renowned inventor. Funny thing, his interest took him to his baby sister’s doll and tore it to see what made the eye to close.  In another incident, he almost burnt the whole house down when he tried cooking rocket oil from saucepans.

Johnson enrolled at Williamson High school, a facility that admitted blacks ONLY.

Students used to call him an engineer.’ He represented his school in Alabama science. He was the only person of color. He developed a robot named ‘ Linex,’ powered by compressed air. It took home the first prize.

Johnson attended Tuskegee University, where he obtained a B.S in mechanical engineering and a master’s degree in nuclear engineering.

Personal Life

Johnson is a married man to Linda Moore. They have four lovely children and reside in Georgia, USA.

Johnson is the board head of Georgia Alliance for Children. He is also an associate of 100 Black Men of Atlanta, a body that provides mentorship to both High school and college students.

Age, Height, and Weight

Being born on October 6, 1949, Lonnie Johnson is 74 years old as of today’s date [current date]. His height is 5 feet, 9 inches tall, and his weight is 83 kg.


From 1971 to 1991, Johnson worked at NASA on various experiments such as Air Force Mission Lab. He worked as an engineer of Mariner Mark II Spaceship for Comet Rendezvous and Saturn Orbiter Probe.

He started his firm known as Johnson Research and Development, in which he is the manager.

Not so far, Johnson collaborated with a team of scientists from Tulane University and Tuskegee University to come up with a way of converting heat energy into electricity to make greener energy easily accessible.

Johnson owns two technology developed entities, namely, Excellatron Solid State and Johnson Electro-Mechanical Systems (JEMS). They are both found in Sweet Auburn in a neighboring Atlanta.

The Excellatron firms entail the development and manufacture of batteries in the solid-state, specifically thin in size. The cells are characterized by:

  1. a) Ability to hold high temperatures
  2. b) Extended life cycle
  3. c) Thin, flexible profiles, among many other characteristics.

On the other hand, the JEMS has manufactured the Johnson thermal-Electrochemical Converter System (JTEC). It is widespread among mechanics.

It listed among the top ten inventions done in 2009. The primary function of the system is to turn heat energy into electrical energy. It works by passing hydrogen ions through two surfaces, and this is the most effective way when compared to other methods.

Johnson is among few Black American inventors whose efforts contribute at large to all inventions registered by the government of the United States.

Awards & Achievements

Johnson’s work could not go unrewarded since he has done a lot in the science field. In 2008, Johnson received Breakthrough Award from a science magazine known as ‘Popular Mechanics’ for his contribution to JTEC. In 2011, the project ceremoniously inaugurated into the State of Alabama Engineering Hall of Fame.
