Normally I would agree with you except that Obama Sr was a high profile student and those in class with him would remember the tall, English accented speaking exchange student. Sr often was interviewed for his views and thoughts and he also went to many places to give speeches and relay information about Kenya. In a class of 24 he would definitely be memorable.
Also a student was interviewed who took the Russian language class a few years later. That student said that the teacher would have been one of two women, either Ella Lury Embree Wiswell or Isabella Tripianky. Try and find any information on Isabella Tripianky and you will discover that she is only found on a blog and in an excerpt for a book, nothing more can be found about her and she isn’t listed anywhere else. Ella Lury Embree Wiswell can be found mentioned on the memorial page for UH at Manoa even though she retired from teaching in 1968 and yet she is listed as the French teacher not the teacher of Russian.
I appreciate all the digging and reporting you've been doing on behalf of our republic and all its good people.
I thought he was short. How tall was he? I saw a picture and he looked very short.
