In many podcasts that touch on the theme of design patterns, this name pops up sooner or later. I remember this man deservedly, but often not at all in that context.
Christopher Alexander, in collaboration with five other architectural specialists, actually wrote a book on architectural patterns, in which he actually reviewed over two hundred of these. The short and widely known title of this book is “A Pattern Language”. However, it is enough to look at the cover of the book to see its full name: “A Pattern Language: Towns, Buildings, Construction”. Such long titles of books and the wide prevalence of only short names are not uncommon; for example, everyone knows the "Origin of Species" by Sir Charles Darwin, but rarely can anyone recall its full name: "The Origin of Species by Natural Selection, or the Preservation of Favorable Races in the Struggle for Life"
So the book of Christopher Alexander in the field of software development has absolutely nothing to do. It is devoted exclusively to issues of urban planning, space construction, urban communities and architecture in general. The book is incredibly interesting and fascinating - I strongly advise you to read.
