Dr Martin Cooper who made the first mobile phone call
Dr Martin Cooper: Motorola researcher who made the first mobile phone call on April 3rd 1973

On the 3rd of April 1973 the very first mobile phone call was made using a wireless hand held phone. The call was made by Motorola researcher and executive Dr. Martin Cooper to his rival Dr. Joel Engel from Bell Labs (which eventually became part of Nokia).

The prototype mobile phone used by Dr. Cooper weighed a whopping 2kg and measured 23x13x4.5cm. The battery life of the prototype offered just 30 minutes of talk time from a 10 hour charge. Whilst wireless calling technology had existed in trains and some luxury cars since the 1920s and 1959 respectively this was the first call from a hand held device. Dr Cooppers research has helped paved the way for the modern smart phones used globally today.
