HENDRIK ANTOON LORENTZ (1853 – 1928)
Hendrik Antoon Lorentz
(1853 – 1928) Dutch
theoretical 
physicist,
professor at Leiden He
investigated 
the
relationship 
between
electricity, magnetism, and
mechanics In order to
explain the observed effect
of magnetic fields on
emitters of light (Zeeman
effect), he postulated the
existence of electric charges
in the atom, for which he
was awarded the Nobel Prize
in 1902 He derived a set of
transformation equations
(known 
after 
him, 
as
Lorentz 
transformation
equations) by some tangled
mathematical arguments,
but he was not aware that
these equations hinge on a
new concept of space and
time
