You are wrong.
I looked at the US News top mathematics graduate programs, and went to each website:
http://math.harvard.edu/graduate/index.html" : Mathematics is an international subject in which the principal languages are English, French, German, and Russian. Almost all important work is published in one of these four languages, although much Russian work is translated into English. Accordingly, every student is advised to acquire an ability to read mathematics in French, German, and Russian, as soon as possible, and is required to demonstrate it by passing a two-hour, written examination in each of two of these three languages.
http://math.mit.edu/graduate/program-structure.html": While there is no Institute Langauge Requirement, doctoral candidates in the Department of Mathematics (both Pure Mathematics and Applied Mathematics) have to demonstrate a mathematical reading knowledge in at least one of the following languages: French, German, Italian, Russian, Spanish or Chinese.
http://www.math.uchicago.edu/graduate/index.shtml" : Each student is also required to pass an exam in a scholarly language other than English (usually in French, German, or Russian).
http://math.berkeley.edu/graduate_phd.html" : Pass one language examination in French, German, or Russian.
http://www.math.princeton.edu/graduate/" : The student satisfies the language requirement by demonstrating to a member of the mathematics faculty a reasonable ability to read ordinary mathematical texts in at least two of the following three languages: French, German, and Russian. One language test must be passed before the end of the first year, and the second before completing the general examination.
Stanford: None
Caltech: None
http://www.yale.edu/bulletin/html/grad/math.html" All students are required to: (1) complete eight term courses at the graduate level, at least two with Honors grades; (2) demonstrate a reading knowledge of two of the following languages: French, German, or Russian;
http://www.math.columbia.edu/programs/main/graduate/index.html" : Also required is a reading knowledge of one language, chosen from French, German, and Russian.
NYU: None
http://www.math.lsa.umich.edu/graduate/phd.shtml": To ensure that, during their careers, students have access to mathematics written in languages other than English, all students are required to demonstrate a reading knowledge of mathematics in one of the remaining major scientific languages; French, German, and Russian.
http://www.gdnet.ucla.edu/gasaa/pgmrq/math.asp" : Prior to taking the oral qualifying examination for advancement to candidacy, students in the pure program must fulfill the foreign language requirement. Students must pass one written departmental language examination in either French, German, or Russian. These foreign language examinations, offered Fall and Spring quarters, require the translation of material in some basic field of mathematics. The examinations may be taken any number of times until passed.
Maybe I should check out some of the lower ranked schools. So I went to page 4, and in order:
http://www.math.ksu.edu/main/graduate/advanced_degrees.htm#FLE" : In addition to the QE and SE, each Ph.D. candidate will be required to pass a language examination in French, German or Russian. No substitute foreign languages will be allowed. The requirement must be completed at least seven months prior to the final examination and may be met in one of two ways:
http://math.syr.edu/GradPhDMath.htm" : All students seeking the Ph.D. in Mathematics must demonstrate proficiency in one of French, German, or Russian.
http://www.math.temple.edu/grad/grad2_handbook_1999.html" : The foreign language requirement for the Ph.D. degree is that each student shall have the reading knowledge in two of the following five languages: Chinese, French, German, Japanese, and Russian.
http://www.tufts.edu/as/math/phd.html" : Also, the student is required to pass a brief language examination, consisting of translating a few pages of mathematical text from French, German or Russian to English.
Tulane: None
http://www.math.ucsc.edu/Graduate/programs.html#flr" : Graduate students in the Ph.D. program are required to demonstrate a knowledge of French, German or Russian sufficient to read the mathematical literature in the language. A foreign language examination may be administered by any member of the Mathematics faulty. The examination can be either oral or written. The foreign language requirement must be satisfied before advancement to candidacy for the Ph.D. degree.
I think you get my point.
U Kentucky: Students should satisfy the Foreign Langauge Requirement described
under “General Requirements for all Masterʹs Degrees” in the Graduate School
Bulletin (pg. 22 of the Spring 2005 edition). Acceptable languages are ordinarily Chinese, French, German, and Russian.
I think that will do for now.
