Brief History:

Bones was founded by Sunrise staff members Masahiko Minami, Hiroshi Ōsaka and Toshihiro Kawamoto in October 1998. One of their first projects was collaborating with Sunrise on Cowboy Bebop: Knockin' on Heaven's Door, a feature film based on the Cowboy Bebop anime series.
In 2007, the studio suffered the loss of co-founder Hiroshi Ōsaka, well known for his works as character designer on series such as Mobile Suit Victory Gundam, Mobile Fighter G Gundam and The Mars Daybreak. Ōsaka had been battling with cancer, and died from the disease on September 24, 2007. He was 44 years old.
Since the death of Ōsaka, two new additions have been made to the studio's board of directors: Makoto Watanabe and Takahiro Komori. Komori is well known as a character designer and animator who has been with the studio since its inception. His previous works as designer consist of Angelic Layer, Scrapped Princess, and Darker than Black.

Ryne's Take:

Bones is a more modern studio. Their works are kinda a hybrid, of adapting manga/light novels and original productions. They were the main studio that helped being the classic manga of Fullmetal Alchemist to life. For me this was the first work that I saw from the studio. While looking at all the works they have made and continue to make I am amazed at the hits they have had. More recently Studio Bones are the ones adapting the wildly successful Shojen Jump manga My Hero Academia which is soon getting its 5th season in 2021. Studio Bones is definitely one of the newer front runners in the modern animation.
