I had the absolute privilege of having Michael as a grandfather, and will forever treasure the memories of growing up and visiting Grandad Michael in Knighton. He was a truly kind man with a humorous streak a mile wide, an enormous breadth of knowledge, and a frankly impressive love of lemon curd. The world was the better for his living on it. Hopefully he forgave me for the time I sent shards of hazelnut all over his and Mary’s front room as a small child – I can only imagine how essential slippers were in the aftermath. I’m glad I got to know him, and to hear how he touched so many lives. We’ll all miss you, Grandad….

Such a kind and patient man, with such a great sense of humour. Sermons with Tatty Ratty are a particularly bright childhood memory….

Michael will be deeply missed as both a colleague and a friend.  He had a gift for making one think differenty, always willing to engage in thoughtful discussions and to question conventional assumptions.  Beyond his legacy in thermal comfort, I will remember Michael for his kindness, humor, mentorship, and the unmistakable twinkle in his eye.  I have a fond memory of him staying at my home in California when my children where young, and teaching my daughter Carolyn how to carefully peel an orange so that the peel comes off whole, in the shape of an elephant’s head and long trunk.  She still loves doing that.  A legacy of a different kind perhaps!…

Very sad to hear the news that Mike has died. I had the privilege of working with Mike at Oxford Brookes University from 1996 to 2003 where I was first introduced to his and Fergus’s pioneering work on adaptive thermal comfort. Mike was always supportive of everyone in the department and commanded huge respect for his insights. On a personal level, I found him to be a great calming influence and always valued his opinions. He will be greatly missed….

My deepest condolences to the family of Dr. Michael Humphrey. He will be missed and cherished for his seminal work in the field of thermal comfort for 6 decades. At one of the early Windsor conferences, I was lucky enough to sit near him and asked: “how are we going to get more data on how people feel in naturally ventilated places?” With that twinkle in his eye and gentle demeanor, he launched into all sorts of analyses that could be done. I will always remember his thoughtfulness about nudging standards along in the US and guiding many young researchers to think holistically about the environment. Here’s to a life well-lived!…

I was deeply saddened to hear of the passing of Dr. Michael Humphreys. Dr. Humphreys was one of the great pioneers in the field of thermal comfort, and especially in the development of the adaptive thermal comfort approach. His papers in the 1970s had a profound influence on many of us. I also remember very clearly the first Windsor Conference, where Dr. Humphreys engaged in warm but serious and passionate discussions with Professor Fanger and other colleagues about different approaches to understanding thermal comfort. Although there are many ways to study and evaluate comfort, Dr. Humphreys taught us something very important: that we should always place the people inside buildings at the centre of our thinking. His words have stayed with me for many years: “If a change occurs such as to produce discomfort, people react in ways that tend to restore their comfort.” This simple and profound insight continues to be highly relevant today. It reminds us that occupants are not passive recipients of the indoor environment, but active human beings who respond, adapt, and seek comfort. I will remember Dr. Humphreys not only as a leading scholar, but also as a warm and thoughtful person whose work…

Melia and I got to know Michael and Mary when Melia.was the Vicar of Knighton 2012-18.    Michael and Mary were pillars  both of the Baptist   church and the whole Knighton Christian  community.    I was very grateful to Michael for beginning and running the Theology Circle for many years, and I also want to acknowledge his help when I was Chair of Churches Together in Knighton in the task of setting up that body as a registered  charity  – so that we could support Knighton Food Bank amongst other good causes.  Michael was a wonderful exemplar of the Christian life – completely committed, very disciplined in his approach, yet very warm and  compassionate.  May he rest in peace and rise in glory!    …

I came to know Prof. Michael when I started my PhD research on adaptive thermal comfort at the Indian Institute of Technology Delhi, India, around 2006-2007. To start, I wrote him a detailed e-mail outlining my ideas and future research data collection and analysis, which led to writing manuscripts. I am sure that, despite his busy schedule and humility, he reviewed my e-mails and agreed to my request to correct my manuscripts.  Eventually, he helped me by correcting and giving his comments to improve the research manuscripts. One of the manuscripts he corrected was among the hottest articles in the Building and Environment Journal in 2010, and another one published in the Applied Energy Journal in 2011. These two manuscripts enhanced my understanding of adaptive thermal comfort and are very close to my heart. I did not get the opportunity to meet Prof. Michel in person, but whenever I wrote to him, he replied, and I could feel the warmth and support in his responses. His contribution to the field of adaptive thermal comfort research community will never be forgotten. The news of his departure is very, very sad, and I am sure that his noble soul will rest in eternal…

Michael and Mary gave us, and our baby daughter, a warm welcome to the congregation at High Street Baptist Church, Tring back in 1983 – and over 40 years and 4 ministers later I am still there! Michael dedicated our three younger children, Mary looked after the creche and all of us were entertained by Michael’s children’s talks with ‘Tatty Ratty’. Many years after the Humphreys had left Tring and were in Knighton, our youngest was at university in Aberystwyth and it was a delight to call in on them and see where they had made their new home. Having kept in touch over the years, and having learned from our Christmas updates that I had become involved in campaigning on climate change – and creation care within the church – Michael periodically contacted me about his work on thermal comfort and it was always informative and useful to hear from him. My husband and I remember both Michael and Mary with great fondness….
