Who was the first to put a downforce wing on a racecar?

Norman Graham Hill (GBR) (Gold Leaf Team Lotus), Lotus 49B - Ford-Cosworth DFV 3.0 V8 (RET)
Joseph "Jo" Siffert (SUI) (Rob Walker/Jack Durlacher Racing Team), Lotus 49 - Ford-Cosworth DFV 3.0 V8 (finished 11th)

No. 16: John Surtees (GBR) (Honda Racing), Honda RA301 - Honda RA301E 3.0 V12 (finished 2nd)

Graham to Jo siffert after he parked his Lotus 49B on the side of the road to retire due to a halfshaft problem.

I would think that's an air brake rather than a downforce device. The panel has a cut out in it that allows it to be rotated to the vertical. That would give a large drag force to both slow and stabilise the car. They didn't have great brakes back then...

Unless they are referring to the wing like fenders I don't see them...

Yes, that's exactly the reference.
Early days of experimenting (outside the box) with all ideas, something that is lacking these days with convergence, parity and regulations wound up so tight ......
With Hill's car having the rear wing and the others the front 'winglet', something I had never seen before, but downforce nonetheless.

Could be both of course, but I cannot make out any mechanism to tilt on the run.

This topic relevant article may also be of interest: http://www.allpar.com/model/superbird.html

Back in early 1965, a windtunnel test program was carried out, & aerodynamicist Jim Amick duly noted:

"The divergence speed for a given combination of spring rates can be increased indefinitely by the installation
of a horizontal airfoil at the rear of the vehicle."

Jim Hall received a copy of this report, & so had a scientific evidence base - for his empirical wing use.

very interesting article, thank you

Yes, It was the Chaparral in the WC prototypes. The following year ing Forghieri (Ferrari) introduced it in Formula 1."

These are my memories. I saw the Chaparral at the Targa Florio (1966? or 1967?). The wing was mobile, commanded by the pilot that during braking and acceleration made him assume a high incidence and then in speed brought him back to normal position (the same effect as the current DRS)

JUST wondering if anyone noticed the whole wing has been ripped off !

You can see Ferrari (P3?) and Chaparral at Targa Florio 1967. I was here!!

That is a thrill.
Good camera and helicopter work for 1967

according to Doug Nye .....
the first F1 car with a (rear) wing was Jim Clark's Lotus 49 in the Tasman winter 67-8 series
JC's wanted to try such so mechanics Leo Wybrott, Dale and Roger Porteous strut-mounted a length of helicopter rotor blade
it appeared in practice for 3 events but was not raced as JC didn't want to upset ACBC back home
it was repeatedly photographed by Gianni Marelli of the Ferrari (Amon's) team
(Michael May of winged May 1955 Porsche notoriety was of course a consultant for Ferrari eg for the F1 DI)
front DF devices on fast circuits were established in F1 in 1967

btw
spoiler (on a car) is a meaningless buzzword
no car ever had a rear spoiler - a spoiler spoils lifting flow by being in the middle of a lifting surface (not at the end)
spoilers appeared with jet airliners - coincidentally just the time car people started their aero interest
