Unfortunately, this seems to be another case of "there aren't any pictures of the people involved". Therefore you will have to make do with the ones involved in the process and guess the theme. I'll mention the other biologists when I give you the answer in the next installment. This guy definitely got the ball rolling though.
The answer to the last installment was Frederick Sanger who developed the DNA sequencing method that used dideoxy chain termination. This method is still used to this day and it was instrumental in completing the human genome and Fred himself was one of the first people to complete a genome when he sequenced the virus Phage Φ-X174. In honour of his contribution to sequencing an institute in Hinxton was named after him as the Sanger Institute which is one of the world's leading centres for genomic-based research. He's also one of only a handful of people to have won two Nobel prizes.
