Boris Tellegen aka Deltainc was born in 1968, in the Netherlands.
He became one of the pioneers of the European graffiti movement, in 1984, when he made his tag DELTA for the first time. His work shows the hallmark of his time at the Faculty of Industrial Design at the Technical University Delft, from where he graduated with a degree in Industrial Design Engineering in 1994.
The first DELTA tag appeared on the streets in 1984: through the years this Netherlands based artist has developed a complex and unique style that resembles isometric plans and plays with ideas of architecture and high tech futuristic vehicles. Boris introduced an alien and idiosyncratic aesthetic into graffiti art that escapes the common logo-like word IDs. He influenced writers all over the world for decades with his 3D letter style.
