Michel Marcel Navratil Jr. (12 June 1908 – 30 January 2001) was a French philosophy professor who was one of the last survivors of the sinking of Titanic on 15 April 1912.

After buying White Star Line tickets in Monte Carlo, they travelled to England where they boarded the RMS Titanic.

For the journey, using a stolen passport, Navratil assumed the alias "Louis M. Hoffman", and the boys were booked as John and Fred.

He let the boys out of his sight only once, when he allowed a French-speaking woman, Bertha Lehmann, to watch them for a few hours while he played cards.

French-speaking first-class passenger Margaret Hays cared for them at her house until their mother could be located, which occurred as a result of newspaper articles which included their nicknames.

"Michel attended college and in 1933 married a fellow student, Charlotte Lebaudy-Blanc, and they later had two daughters, Élisabeth and Michèle.

[9][10] Throughout his life, he maintained that his brush with death at such a young age, coupled with the loss of his father, strongly influenced his thought processes.

The following year, he joined ten fellow survivors at a Titanic Historical Society convention in Boston, Massachusetts.

In 1996, he joined fellow survivors Eleanor Shuman and Edith Brown on a cruise to the location of the wreck, where attempts were made to bring a large portion of the hull to the surface.

Reacting to the scene of passengers freezing to death in the icy waters, he stated that he hoped his own father had not suffered for too long before dying.
