From Online Etymology Dictionary:
late 14c., matris, matrice, “uterus, womb,” from Old French matrice “womb, uterus” and directly from Latin mātrix (genitive mātricis) “pregnant animal,” in Late Latin “womb,” also “source, origin,” from māter (genitive mātris) “mother” (see mother (n.1)).
The many figurative and technical senses are from the notion of “that which encloses or gives origin to” something. The general sense of “place or medium where something is developed” is recorded by 1550s; meaning “mould in which something is cast or shaped” is by 1620s; sense of “embedding or enclosing mass” is by 1640s.
The mathematical sense of “a rectangular array of quantities (usually square)” is because it is considered as a set of components into which quantities can be set. The logical sense of “array of possible combinations of truth-values” is attested by 1914. As a verb, in television broadcasting, from 1951.”
Dr. Malcolm Pines, in a) New Developments in Group Psychotherapy: Dialoging with Deeper Aspects of Self Through the Group Matrix:
” (quoting S.H. Foulkes) “Just as the individual’s mind is a complex of interacting processes (personal matrix), mental processes interact in the concept of the group (group matrix), thus in the group what is reproduced is basically the matrix of evolving personality“.
and in b) “BURROW, TRIGANT (1875-1950)” at encyclopedia.com:
“A forgotten American psychoanalyst and pioneer of group analysis, Trigant Burrow was born in Norfolk, Virginia, on September 17, 1875, and he died on May 25, 1950, in Westport, Connecticut…
Burrow and his followers formed the Lifwynn Institute (Foundation for laboratory research in analytic and social psychiatry) in Westport, Connecticut, which has carried on his work.
Burrow’s psychoanalytic and group analytic work anticipated the findings of much later workers. Sigmund Henrich Foulkes, the founder of group analysis, acknowledges his influence, having read his work in 1926. Many of the techniques of group therapy and of the encounter group movement originate from Burrow and his group laboratory. He wrote seven books and seventy articles, and had this comment: “Psychoanalysis is not the study of neurosis: it is a neurosis,” but for Freud he was a “muddled bubbler” (letter to Sándor Rádo, September 30, 1925).”
Edi Gatti Pertegato writes in Group Analysis 47(3) (2014):
“…Pat de Maré (1972)…
points out that ‘Trigant Burrow recognized the significance of the interactive matrix of society for individual growth, “phylic” [or group] cohesion’; conceived ‘the individual as a “socius”, as part of the larger sociological structure’ (de Maré, 1972: 21)
states that it was ‘Burrow who first coined the term “group analysis”’, and emphasizes that ‘we may still have much to learn from his writings’ (de Maré, 1972: 62).”
