We study a conjecture of Grothendieck on bilinear forms on a C∗-algebra Ol. We prove that every “approximable” operator from Ol into Ol∗ factors through a Hilbert space, and we describe the factorization. In the commutative case, this is known as Grothendieck's theorem. These results enable us to prove a conjecture of Ringrose on operators on a C∗-algebra. In the Appendix, we present a new proof of Grothendieck's inequality which gives an improved upper bound for the so-called Grothendieck constant k G.
