The author of "mammalampa’s" collection of lamps and its signature designs is designer, Ieva Kaleja (1978). She has obtained a Bachelor’s degree in Visual Art in Latvia and a Master’s degree at the Domus Academy in Milan. Her work is characterised by the fusion of art and design. In her creative work, she has chosen to step outside the realm of virtual thinking; she finds real things and new ways of applying natural materials, thus forming her signature style. She offers a new aesthetic, in which the natural harshness of materials is contrasted with their perfect refinement. This is characterised by the contemporary interpretation of "handmade", i.e. not replacing machines, but finding those items which machines cannot provide, nuances of refining materials through natural processes.
The brand’s designer and creative director Artis Nimanis established an&angel in 2004. The first works were created as his Master’s Thesis at Art Academy of Latvia, but when he received plentiful requests from friends, asking to produce more bowls for their homes, he realised the future potential of his work. Since then Nimanis has been developing crystal and glass creations that are minimalist in their aesthetics, functional in their design and unique by virtue of their hand-crafted nature. He is active as an independent glass artist, his latest personal exhibitions took place in Washington, D.C. and in the Franz Mayer Museum in Mexico, where he returned early 2016 with a huge personal exhibition in Galeria Ethra.
