Tony Carpenter was one of the original twenty-three characters invented by the creators of "EastEnders", Tony Holland and Julia Smith. Tony was originally intended to be named Alan, and his son Kelvin Carpenter was originally named Kevin. They were the first black characters to appear in the soap. Black and Asian characters were two ethnic minorities that had previously been under-represented in British soap before "EastEnders" aired. Holland and Smith knew that for the soap to succeed there needed to be a varied group of characters, so that several different sections of the audience had someone to identify with. Additionally, if the programme was to be realistic, it had to reflect the cross-section of society that actually existed in the real location. For these reasons, different sexes, ages, classes, religions and races were all included in the original character line-up. Both Holland and Smith had been at the forefront of the move towards 'integrated casting' in television and had encountered an array of ethnic diversities in the process. Even though the ethnic minority groups were deemed the hardest to research, Holland and Smith called upon their contacts to relay information about their origins and lifestyles and were then able to portray Walford's most recent immigrants more realistically.
