The Story Behind the Darwin Trust

Every year, as I sit in the audience of the Murray Lecture, I am reminded of the profound story behind the Darwin Trust—the organization funding my PhD. A tale that not only inspires but reaffirms the translational impact of science.

The trust owes its existence to the pioneering work of Noreen and Kenneth Murray, a couple whose contributions to molecular biology revolutionized the field. 

Both Noreen and Ken were PhD students at the University of Birmingham, where they met each other for the first time. Their shared passion for science blossomed into a lifelong partnership, and the two married in 1958. Following a post-doctoral stint at Stanford University in 1959, the couple returned to the UK and, in 1968, became part of the newly established Department of Molecular Biology at Edinburgh University. 

In the early 1970s, they led the development of recombinant DNA technology, a groundbreaking innovation that laid the foundation for genetic engineering as we know it today. Noreen and Ken had become interested in restriction enzymes, proteins that cleave DNA only if it has a particular short stretch of nucleotide sequence known as a restriction site. Some of these enzymes cut DNA at their recognition site creating the possibility of breaking DNA molecules at defined sites and joining together fragments of different molecules that had been cut in this fashion. Noreen used her skills as a geneticist to select variants of bacteriophage (bacterial virus) lambda that only had restriction sites in a region that was not essential for its growth. These lambda vectors could be cut at the remaining sites and foreign DNA could be inserted producing recombinant molecules that could further be amplified in bacteria.

Noreen assessed that inserting foreign genes into bacteria might allow production of profuse amounts of the corresponding proteins for experimental and therapeutic purposes.

The Murrays created the first approved hepatitis B vaccine for human use, a breakthrough that brought Edinburgh and the UK to the forefront of scientific research. Kenneth Murray co-founded the biotech company Biogen, which patented the vaccine.

Murray used his share of the royalties from his vaccine to establish the Darwin Trust, which supports education and research in natural science till the day. 

The Murrays’ contributions were not just a step forward for science but also a testament to the social values embedded in their work. 

I feel, this transcending course of science, the way a discovery in the lab impacts lives, saves some, creates some, is revolutionary in its true sense. And this is what keeps one going at 8 pm on a Friday in the lab when experiments fail, but hope doesn't.
