Giovanni Carlo's pictures, which mostly went to the Pitti were varied; but Leopold's were chiefly portraits of artists, wherever possible painted by themselves, a collection which is steadily being added to at the present time and is to be seen in several rooms of the Uffizi, and those miniature portraits of men of eminence which we shall see in the corridor between the Poccetti Gallery and Salon of Justice at the Pitti.

Cosimo III (1670-1723) added the Dutch pictures and the famous Venus de' Medici and other Tribuna statuary.
The galleries remained the private property of the Medici family until the Electress Palatine, Anna Maria Ludovica de' Medici, daughter of Cosimo III and great niece of the Cardinal Leopold, bequeathed all these treasures, to which she had greatly added, together with bronzes now in the Bargello, Etruscan antiquities now in the Archaeological Museum, tapestries also there, and books in the Laurentian library, to Florence for ever, on condition that they should never be removed from Florence and should exist for the benefit of the public.

Her death was in 1743, and with her passed away the last descendant of that Giovanni de' Medici (1360-1429) whom we saw giving commissions to Donatello, building the children's hospital, and helping Florence to the best of his power: so that the first Medici and the last were akin in love of art and in generosity to their beautiful city.
The new Austrian Grand Dukes continued to add to the Uffizi, particularly Pietro-Leopoldo (1765-1790), who also founded the Accademia.

To him was due the assembling, under the Uffizi roof, of all the outlying pictures then belonging to the State, including those in the gallery of the hospital of S.Maria Nuova, which owned, among others, the famous Hugo van der Goes.

It was he also who brought together from Rome the Niobe statues and constructed a room for them.
