Ah, you visited Niemayer, designer of buildings looking like something from outer space...
His daughter understood a lot about ergonomy, influenced what people in the world expect from furnishings to sit on. Generally I am more her fan...

Anna Maria Niemeyer got not much older than 80 jears. Guess Oscar Niemeyer was the prominent person that lived longest since Methusalah, but he would not survive his only child for more than a few moths.
Some people will say that stuff like the Alta and Rio chairs are Oscars work as they where created as part in his buildings -- this is likely why you dont know her. She simply was a long time a colaborateur on dad's payroll rather than a designer traded by her own name.
