Received 16 March 1994

Highly accurate results are presented for the susceptibility χ(T) of the s=1/2 Heisenberg antiferromagnetic chain for all temperatures, using the Bethe ansatz and field theory methods. After going through a rounded peak, χ(T) approaches its asymptotic zero-temperature value with infinite slope.
