  • Polhem Prize

    The Swedish Association of Graduate Engineers

    Everything that is connected needs to exchange information. Twenty years ago, Daniel Stenberg started working on what we now call cURL. Since then he has spent late evenings and weekends, doing unpaid work to refine his digital tool. It consists of open source code and allows you to retrieve data from home page URLs. The English letter c, see, makes it "see URL".
