Federico Faggin is an Italian-American physicist, engineer, inventor and entrepreneur. He is best known for designing the first commercial microprocessor, the Intel 4004. He led the 4004 (MCS-4) project and the design group during the first five years of Intel's microprocessor effort. Faggin also created, while working at Fairchild Semiconductor in 1968, the self-aligned MOS (metal–oxide–semiconductor) silicon-gate technology (SGT), which made possible MOS semiconductor memory chips, CCD image sensors, and the microprocessor. After the 4004, he led development of the Intel 8008 and 8080, using his SGT methodology for random logic chip design, which was essential to the creation of early Intel microprocessors. He was co-founder and CEO of Zilog, the first company solely dedicated to microprocessors, and led the development of the Zilog Z80 and Z8 processors. He was later the co-founder and CEO of Cygnet Technologies, and then Synaptics.

Simon J. Ortiz is an American writer of the Acoma Pueblo tribe, and one of the key figures in the second wave of what has been called the Native American Renaissance. He is one of the most respected and widely read Native American poets. Ortiz's commitment to preserving and expanding the literary and oral traditions of the Acoma accounts for many of the themes and techniques that compose his work. Ortiz identifies himself less as a "poet" than a "storyteller". The composition of a traditional Pueblo storyteller includes not only oral narrative materials, which adapt easily to short story or essay forms, but also songs, chants, winter stories, sacred oral narratives associated with origin stories and their attendant ceremonies. Such materials when recited aloud, have a distinctly "poetic" texture.
