Roy Henry ("King" Henry) (fl. around 1410) was an English composer, almost certainly a king of England, probably Henry V, but also possibly Henry IV. His music, two compositions in all, appears in a position of prominence in the Old Hall Manuscript.

Musicologists have not been able to agree on which English monarch wrote the two mass movements which appear, at the head of their respective sections, in the Old Hall Manuscript. Henry IV, who reigned from 1399 to 1413, was in his early forties when the music was most probably written, since stylistic evidence places it around 1410. That he was still mentally able at this period, and had leisure time to think and design, is clear from his payment for the metal used in the construction of a cannon made to his own design in 1409 (see Mortimer, Fears of Henry IV, pp. 319-20). In addition, there is more evidence of his being an accomplished musician than his son. One contemporary referred to him as a 'sparkling musician'; he obtanied the first known recorder and both he and his wife played the harp. (His accounts record a number of payments for harp strings: see Mortimer, Fears of Henry IV, pp. 46-7). As Henry V was so busy after his accession - and abroad on campaign continually from 1417 - the sacred composition falls more naturally into his father's twilight years than the son's martial ones. Two other reasons suggest the father as the composer: one would have expected clarification of the name if it had been the second of the two King Henrys; also the connection of the manuscript with the duke of Clarence suggests Henry IV, as Clarence and Henry V were not close whereas Clarence was his father's favourite son.

Roy Henry Vickers, CM, OBC (born June, 1946, in Laxgalts'ap (now known as Greenville), British Columbia) is a Canadian First Nations artist. He owns and operates a gallery in Tofino, British Columbia.

Vickers was born on the Nass River but raised in Kitkatla, Hazelton, British Columbia, and Victoria, B.C. His father was a fisherman who was matrilineally Tsimshian, also with Haida and Heiltsuk ancestry. His mother was a schoolteacher whose parents had immigrated from England and who was in the 1940s adopted into the Eagle clan at Kitkatla, B.C. (making Roy also Eagle). His grandfather was a Kitkatla canoe-carver. The paintings and works that he has created reflect this mixed heritage as his work has many elements of the traditional art of the First Nations peoples of the Pacific Northwest, but remains quite distinctive.

Vickers became interested in Northwest Coast art partly under the influence of the anthropologist Wilson Duff.

First Nations is a term that collectively refers to various Aboriginal peoples in Canada who are neither Inuit nor Métis. There are currently over 630 recognized First Nations governments or bands spread across Canada, roughly half of which are in the provinces of Ontario and British Columbia. The total population is nearly 700,000 people. Under the Employment Equity Act, First Nations are a "designated group", along with women, visible minorities, and persons with physical or mental disabilities. They are not defined as a visible minority under the Act or by the criteria of Statistics Canada.

The term First Nations (most often used in the plural) has come into general use for the indigenous peoples of the Americas located in what is now Canada, except for the Arctic-situated Inuit, and peoples of mixed European-First Nations ancestry called Métis. The singular, commonly used on culturally politicized reserves, is the term First Nations person (when gender-specific, First Nations man or First Nations woman). A more recent trend is for members of various nations to refer to themselves by their tribal or national identity only, e.g., "I'm Haida," or "We're Kwantlens," in recognition of the distinctiveness of First Nations ethnicities.

Norval Morrisseau, CM (March 14, 1932 – December 4, 2007), also known as Copper Thunderbird, was an Aboriginal Canadian artist. Known as the "Picasso of the North", Morrisseau created works depicting the legends of his people, the cultural and political tensions between native Canadian and European traditions, his existential struggles, and his deep spirituality and mysticism. His style is characterized by thick black outlines and bright colors. He founded the Woodlands School of Canadian art and was a prominent member of the “Indian Group of Seven”.

An Anishinaabe, he was born March 14, 1932 on the Sand Point Ojibway reserve near Beardmore, Ontario. Some sources quote him as saying that he was born in Fort William, now part of Thunder Bay, Ontario, on the same date in 1931. His full name is Jean-Baptiste Norman Henry Morrisseau, but he signs his work using the Cree syllabics writing ᐅᓵᐚᐱᐦᑯᐱᓀᐦᓯ (Ozaawaabiko-binesi, unpointed: ᐅᓴᐘᐱᑯᐱᓀᓯ, "Copper/Brass [Thunder]Bird"), as his pen-name for his Anishnaabe name ᒥᐢᒁᐱᐦᐠ ᐊᓂᒥᐦᑮ (Miskwaabik Animikii, unpointed: ᒥᐢᑿᐱᐠ ᐊᓂᒥᑭ, "Copper Thunderbird").
