Martin Luther clearly taught double predestination as he refuted the Roman Catholic Erasmus.
From Martin Luther's 'Bondage of the Will' -
"And it is this very state of the truth, that of necessity proves "Free-will" to be nothing at all; seeing that, the love and hatred of God towards men is immutable and eternal; existing, not only before there was any merit or work of "Free-will," but before the worlds were made; and that, all things take place in us from necessity, accordingly as He loved or loved not from all eternity. So that, not the love of God only, but even the manner of His love imposes on us necessity. Here then it may be seen, how much its invented ways of escape profit the Diatribe; for the more it attempts to get away from the truth, the more it runs upon it; with so little success does it fight against it!" Sect. 101

The first Baptists taught it. I mean "Baptist", not General Baptists, Freewill Baptists nor Fundamentalist Baptists. The 1646 First London Confession is the first to describe baptism as immersion, therefore it is considered the first Baptist Confession.
The 1646 First London Confession of Faith (Baptist)
"God had decreed in Himself, before the world was, concerning all things, whether necessary, accidental or voluntary, with all the circumstances of them, to work, dispose, and bring about all things according to the counsel of His own will, to His glory: (Yet without being the [chargeable] author of sin, or having fellowship with any therein) in which appears His wisdom in disposing all things, unchangeableness, power, and faithfulness in accomplishing His decree: And God hath before the foundation of the world, foreordained some men to eternal life, through Jesus Christ, to the praise and glory of His grace; [having foreordained and]* leaving the rest in their sin to their just condemnation, to the praise of His justice."

Calvin and the Presbyterians believe and teach double predestination.
The 1646 Westminster Confession of Faith (Presbyterian)
"III.
2. Although God knows whatsoever may or can come to pass upon all supposed conditions, (Acts 15:18, 1 Sam. 23:11–12, Matt. 11:21, 23) yet hath He not decreed anything because He foresaw it as future, or as that which would come to pass upon such conditions. (Rom. 9:11, 13, 16, 18)
3. By the decree of God, for the manifestation of His glory, some men and angels (1 Tim. 5:21, Matt. 25:41) are predestinated unto everlasting life; and others foreordained to everlasting death. (Rom. 9:22–23, Eph. 1:5–6, Prov. 16:4)
4. These angels and men, thus predestinated, and foreordained, are particularly and unchangeably designed, and their number so certain and definite, that it cannot be either increased or diminished. (2 Tim. 2:19, John 13:18)"

I too believe in double predestination because it is found in the clear, natural statements of Scripture; and as seen above, I'm in good company in that belief.
