Jean-Yves Tadie probably knows more about Proust than anyone in the world. His work is also controversial. Roger Shattuck actually called for a boycott of the Tadie-edited Pleiade edition of In Search of Lost Time because of the amount of detail and alternative material included (Shattuck's reasons can be found in his Proust's Way). There are currently three large scale biographies of Proust available in English, all titled Marcel Proust: George Painter's (1959 and 1965, still available in a one volume 446 page paperback 2nd edition from Amazon in the UK, and having a reputation for being one of the greatest biographies of the 20th century), William Carter's (2000, 946 pages), and Tadie's (1996, 986 pages). I mention the pages to emphasize the scale of these works.
Two years ago I started reading Proust again. This time I made the breakthrough and was hooked. I am now about two-thirds of the way back to the beginning, somewhere in the middle of Sodom and Gomorrah (volume 4 of 7 in the Modern Library edition). One of the things to know about reading Proust is that once you have been acclimated to the Narrator and his style, resuming the novel is like receiving a telephone call from an old friend. In a page or two it's just like old times.
Shortly, thereafter I read Edmund White's Penguin Life (1999). In his excellent bibliography, he calls Tadie's book the "best biography ever written of Proust". He also notes that at first he "seriously underestimated its worth, since it lacks narrative sweep and humor value and sometimes looks like random notes". I eagerly awaited the English translation.
Meanwhile I began reading Painter and when the Carter book came out started that too. Painter's book reads like a novel. It is beautifully written and funny, like Proust's novel itself. Tadie seems to hold it in disdain, but I intend to go back to it when I finish the rest of Proust. I read about 250 pages of Carter's book. It wasn't that bad but continually consulting the notes I noticed that a large number were references to Tadie. I stopped and decided to wait for the real thing.
I made the right decision. Tadie's book is the real thing. C'est magnifique! The amount of information is staggering, not only about Proust but also about France and the French. If you are going to read a large scale biography of Proust, this is the one. However, the question remains: Is it for everyone?
If you have begun reading Proust and have made your own breakthrough ( i.e. you have finished Swann's Way, a good part of Within A Budding Grove, and intend to keep going) then the answer is a resounding Yes. You have already shown that you can cope with massive detail. You are not intimidated by descriptions of things that you know nothing about (say Hawthorne bushes) but instead look forward to learning about them. This is the book for you, another universe to explore. Not the Narrator's but Proust's and also Tadie's. In the case of Proust , a biography written by a Frenchman seems to have additional advantages.
What if you are new to Proust and want to find out what all the excitement is about? This is not the place to start. First it assumes that you know a lot more than you probably do, both about Proust and his novel. It is true that Tadie's not strong on the narrative. There are also lots of names mentioned: from the novel, from Proust's life, from French culture. It can be hard to follow. Second is the translation. I think Tadie is generally a clear writer. The translation is often confusing. Third, Tadie assumes a certain amount of insider knowledge about French life that a non-native might not possess. Though there are occasional notes, there still remain gaps. Though I view this as an opportunity to learn, it does put some extra stress on a reader unfamiliar with the basics.
My advice? For an overview, if you want one, read Edmund White's short Penguin Life. This will orient you to Proust and his world. But above all begin reading Proust himself. One reviewer dismissed this biography by recommending the novel in place of the biography. Of course. Who would recommend reading a book about Shakespeare before Hamlet, or Joyce before Ulysses? And when you are hooked, which you will become with a little perseverance (trust me, Proust is unbelievably funny as well as profound), then return to Tadie's Marcel Proust and new doors will open for you. And you will find finally that In Search of Lost Time has become a companion for your lifetime.
