His groundbreaking contributions to mathematics and his longstanding relationship with our university, from his extended visit in 1969 and interactions with many of our Combinatorics & Optimization faculty members over the past decades, have left a lasting impact. His approachable demeanor and willingness to engage with budding mathematicians enriched our academic environment immeasurably.
As we reflect on his legacy, we remember not just an exceptional scholar, but a genuinely kind individual who touched the lives of many. Professor Welsh's influence will continue to resonate within the halls of our university and the wider mathematical community.
Our thoughts are with his loved ones. He will be profoundly missed but never forgotten.
