It was Henri Becquerel's father Edmond, who in a book published in 1868, records the earlier work of Niepce de Saint-Victor.
de Saint-Victor in 1857 observed the effect that certain (uranium nitrate) salts could affect photographic plates even in the absence of any visible light. He inferred that the result must therefore be due to some 'invisible rays'.
Becquerel, in association with Marie and Pierre Curie were given the 1903 Nobel Prize in Physics for their research work on radioactivity.
Uranium itself, was first found by a German scientist, M H Klaproth, in 1789, and it was he who named it after the recently discovered planet Uranus.

When scientist discovered radioactivity?
Radioactivity was discovered during 1896 by Henri Becquerel, who was a French scientist when he was working on phosphorescent materials. Other research was done by Becquerel, Ernest Rutherford, Paul Villard, Pierre Curie, Marie Curie, and others afterwards.
Who discovered radioactivity?
henri bacquerel discovered radioactivity in 1896.Artificial radioactivity was first discovered by Joliot Curie and her husband in 1934 while studying the effect of alpha particle bombardment on like elements like Aluminium
What was Henri becquerel contribution?
Further contributionsReturning to the field he had created, Becquerel made three more important contributions. One was to measure, in 1899 and 1900, the deflection of beta particles, which are a constituent of the radiation in both electric and magnetic fields. From the charge to mass value thus obtained, he showed that the beta particle was the same as Joseph John Thomson's recently identified electron. Another discovery was the circumstance that the allegedly active substance in uranium, uranium X, lost its radiating ability in time, while the uranium, though inactive when freshly prepared, eventually regained its lost radioactivity. When Ernest Rutherford and Frederick Soddy found similar decay and regeneration in thorium X and thorium, they were led to the transformation theory of radioactivity, which explained the phenomenon as a subatomic chemical change in which one element spontaneously transmutes into another. Becquerel's last major achievement concerned the physiological effect of the radiation. Others may have noticed this before him, but his report in 1901 of the burn caused when he carried an active sample of the Curies' radium in his vest pocket inspired investigation by physicians, leading ultimately to medical use.For his discovery of radioactivity, Becquerel shared the 1903 Nobel Prize for Physics with the Curies; he was also honoured with other medals and memberships in foreign societies. His own Academy of Sciences elected him its president and one of its permanent secretaries.Lawrence Badash CitationsMLA Style:"Henri Becquerel." Encyclopædia Britannica. 2009.

What year did Becqueral discover the radioactive element uranium?
Uranium was discovered by Martin Heinrich Klaproth, a German chemist, in the mineral pitchblende (a mix of uranium oxides) in 1789. Klaproth confused the oxide with the metal. In 1841 the French chemist Peligot isolated uranium as a pure metal element. Henry Becquerel (also a Frenchman) discovered the natural radioactivity of uranium in 1896.
When did she discover radioactivity?
Marie Curie discovered RADIUM. Sir Henry Becquerel found radioactivity in 1896.
WHO DISCOVered radioactivity in 1896?
Radioactivity was discovered in 1896 by Henri Becquerel, a French scientist, while testing phosphorescent materials with photographic plates. He discovered that, when the plates were covered with black paper, that phosphorescent materials did not affect the plates until he used uranium salts.
Why is Henri becquerel famous?
Henry Becquerel discovered radio-activity.
Who is Henry Becquerel?

How would you describe bequerel's experiments?
Henry Becquerel radioactivity experiment is an example of finding some thing out of surprise without looking for it. The actual experiment is mentioned on the wikipedia page of Henry Becquerel. Once in my Nuclear Engineering class my teacher told that Henry placed his personal belongings into a drawer along with a salt piece of Uranium and photographic plates. The plates got fogged. Henry was curious to know what caused the fogging of the plates. He experimented by placing the things that were present in the drawer earlier one by one along with a photo graphic plate and recorded the results. Well the realted link will take you to a video on the experiment conducted by Henry Becquerel.
What did Henry Becquerel invent?
Henry Becquerel did not invent anything; he discovered radioactivity in 1896. This groundbreaking discovery paved the way for further research into nuclear physics and its applications in various fields. Henri Becquerel was awarded the Nobel Prize in Physics in 1903 along with Marie and Pierre Curie for their work on radioactivity.
How was radioactivity discovered?
Radioactivity was discovered on March 1, 1896, by a French physicist named Henri Becquerel, this discovery is now known as one of the most famous accidental discoveries in the history of physics. Becquerel was then awarded half of the noble prize for physics in 1903, the other half being given to Pierre and Marie Curie for their study of the Becquerel radiation.
