We study an infinite-dimensional Lie algebra B, called local area-preserving algebra for the Klein bottle introduced by C. Pope and L. Romans [Class. Quantum Grav. 7 (1990) 79--109]. We show that B is a finitely generated simple Lie algebra with a unique (up to scalars) symmetric invariant bilinear form. The derivation algebra and the universal central extension of B are also determined.
