Still without an answer
Going For A Stroll.
On a warm spring day in 1944, a man strolled from his apartments on the 4th floor of the building he was living in and proceeded up the avenue toward the giant archways at the end. The building he left was near the opposite end of the avenue by the rail station. In the middle of his walk he stopped for a seat beneath a large chestnut tree that lined the wide through-fare (indeed he believed it to be the widest in the city) and pondered the following bit of interesting information. The building he was staying at was on a street with more then twenty addresses but certainly fewer then five hundred and all numbered one, two, three, four, etc from start to finish. The sum of all the addresses from one right up to, and including, his were exactly half of the sum of all the addresses from one up to, and including, the last.
What is the man's name?
