10. Jenny Holzer
The artist’s focus on the use of language and ideas in public space often producing shocking juxtapositions such as comments on sexual identity and gender relations – “Sex Differences Are Here To Stay” on an unassuming New York movie theatre marquee, for example – or “Abuse Of Power Comes As No Surprise” in gigantic LED lights over Times Square. Holzer is often compared to the American artist Barbara Kruger, who shares a similar affinity for prompting public debate through text.
