Preface
It was in one of those rare rainy days when if you look outside you fall into depression and when, after drinking your coffee you look helpless around in hope that something will stir up your interest and fill the emptiness of heart and mind.
Being in this not at all happy state of mind, I threw my eyes to the shelves of my library and realized that it would be appropriate to put a certain order between the books, which I have not done for years.
On the shelf right to the door, I had a pile of books brought from my little library in Romania. Among the volume to Etymologicum Linguae Latinae from 1775, I noticed a black hardcover Notebook that still looked very old.
I draw it out and noticed that on the label besides some greats, probably "Geometrie", appears a signature and this is « Gheorghe Vrănceanu ».
Well, yes, I remembered, it's about that Notebook of Professor Gheorghe Vrănceanu that Cornel once told me.
Things happened this way.
Between 1955-1959 Cornel Simionescu was appointed assistant at the Department of Analytical and Higher Geometry of the Faculty of Mathematics and Physics at the University of Bucharest. Head of the Department was Professor Gh. Vrănceanu. One day, the professor entrusted him with keeping this Notebook, saying that he hardly saved it, he could not keep it at home because of his wife, his first wife, who has torn a few pages and wanted to destroy the Notebook.
Besides, he himself recorded this incident in the Notebook. His last words on September 10, 1944, are:
My situation is unchanged. Thoughts and thoughts torture my peace day and night. Some of my notes were discovered by Julia and were torn from this notebook. She does not want to accept any of those rules that say that a person has the right to have his own thoughts.
In 1959, Cornel Simionescu moved to Braşov where he was appointed as a professor at the Department of Mathematics of the Polytechnic Institute. Later on, he was elected as Dean of the Faculty of Mathematics at the University of Braşov.
He had a close scientific collaboration with professor Vrănceanu, who was also his Ph.D. advisor. Just more than that.
In those years, Vrănceanu was looking to spend more time with Cornel, he needed his company, he needed to talk with him. Vrănceanu was impressed by Cornel's penetrating reasoning, by his brilliant intelligence.
I think he especially needed his human proximity. The roots of both were in Moldova, Vrănceanu was born in Vaslui County, and Cornel in Bacău, both of whom spoke the Moldavian dialect of the Romanian language.Acad. Gh. Vrănceanu passed away in the year 1979.
When Cornel moved to Braşov, the black Notebook was lost in packs of books, magazines, and papers. Cornel used it as his own notepads, wrote his own mathematical computations, did some drawings and wrote a bunch of poems.
After Cornel's death, his library came to me and I left Romania. For many years I did not have the time to search in this library.
Recently I discovered the article written by professor Solomon Marcus, who was a member of the Romanian Academy, titled «From the memories of Gheorghe Vrănceanu», published in the newspaper “România literară” no. 11 of 2005.
Here is a fragment:
“Seldom among mathematicians, Vrănceanu wrote his memoirs, which he gave for publication to "Scrisul românesc" Publishing House in Craiova. I remember him presenting some fragments in television shows. I cannot forget the evocation of his childhood; was that of a genuine narrator, in the Moldovanian tradition of Creangă and Sadoveanu. Surprisingly, in the late 1970s`, it has been announced the first issue. However, these memories had never seen the light of the print. It seems that someone, probably a member of the family retrieved the manuscript from the Publishing House. Since then, nothing has been known of them.”
Furthermore, Solomon Marcus writes that:
