famous in battle, traditionally (Brazilian spelling of Luisa)
The story
Luiza is a feminine form in the Portuguese, Polish and Romanian branches of the Louis family, whose older Germanic elements mean "famous" and "battle." Tom Jobim composed the song Luiza for the Brazilian television drama Brilhante in 1981. In Brazil, the name also became a shop sign through a radio contest that gave customers a say in the business’s name. Luiza Trajano Donato and Pelegrino José Donato had bought A Cristaleira, a small gift shop in Franca, São Paulo, in 1957; it became Magazine Luiza. Luiza Helena Trajano, the founder’s niece, recalls starting work in her aunt’s shop at twelve, partly to earn money for presents. She later helped plan the larger store’s layout and learned from serving its customers. The public name joins those stories: a song written for a television character, an aunt’s shop renamed with customer participation, and a niece discovering retail while trying to buy gifts of her own.
