Von Helmont did not discover photosynthesis, but his famous experiment with the willow tree planted in a measured fixed amount of soil over several years gave a very good hint for others to conclude.
von Helmont found that the tree gathered weight by being nourished with water, but the weight gain was not coming from the soil the tree was planted in, but for some parts of it from the water used for irrigation. von Helmont concluded that components from air must have played a part in the the weight gain, but was not able to prove that it was carbon dioxide in the air that formed the essential part of the synthesis of wood matter and he did not discover the role that sunlight plyes in the photosynthesis - later others did.
