CeCu{sub 2}Ge{sub 2} orders antiferromagnetically, T{sub N} {approximately} 4K, and {gamma}(T) {approximately} 200 mJ/K{sup 2}{center_dot}mole near 0.5K and P = 0. A pressure of 9.5 kbar has no measurable effect on T{sub N}; reduces slightly the specific-heat anomaly at T{sub N}; and reduces slightly {gamma}(T) below 0.7K. These effects of pressure are in striking contrast to the much stronger effects on other heavy-fermion compounds, e.g., CeAl{sub 3}, URu{sub 2}Si{sub 2} and CeCu{sub 2}Si{sub 2}.
