Japanese engineer Seiichi Miyake came to fame after Google honored him in one of their doodles in March 2018.
But Miyake, who died in 1982, has been instrumental in paving the way for the blind since 1965.
His tactile tiles line crossings at subways and rail lines throughout the world.
Miyake invented the tiles after a friend started losing his sight. Using his own money, Miyake created tiles that warned of caution (the dotted tiles) and gave direction (the bar tiles.) In two years, his tiles were installed in Japan and by the 1980s they were a fixture worldwide.
Today, even guide dogs are trained to understand these tiles.
