Hello!
American inventor, Maria E. Beasley (née Kenny) has filed numerous patents for her creations. In particular, she is the creator of a lifeboat used on the Titanic, which saved many lives.
In 1880, Maria Beasley decided to create an innovative lifeboat that would be an evolution of the very basic lifeboats of the time and would be "fireproof, compact, safe and easily deployed". Her new design includes metal railings and rectangular floats. Folding and unfolding, Maria's lifeboat is compact and easily stored. Patented in 1882, Maria's invention was also presented at the Universal Exhibition of Industry and Cotton in 1884
Her lifeboats will be used in 1912 on the Titanic. Although installed in insufficient number in relation to the number of passengers, they save a large number of lives when the shipwrecked.
